A suicide bomber who blew up a bus in Bulgaria last week, killing five Israeli tourists, was backed by an organized group who helped him plan and carry out the attack, Bulgarian Prime Minister Boiko Borisov said on Tuesday.
Borisov said police had not yet identified the bomber, who along with the Bulgarian bus driver also died. More than 30 people were wounded in Wednesday's attack at Burgas airport.
Borisov said the perpetrator had not acted alone.
"These are extremely experienced people who have followed strict conspiracy rules," Borisov told reporters after meeting John Brennan, a U.S. counter-terrorism adviser to President Barack Obama.
"From what we see, they arrived nearly a month beforehand, changed rental cars, and traveled to different cities ... and not more than one of the people we are looking for was captured on either security camera," Borisov said.
He declined to give more details on the plotters.
"There was absolutely no chance of preventing such an act of violence," Borisov insisted, according to The Associated Press. "We could have only detected it by chance or if we had been informed by the services that such activities were under way in Bulgaria."
An explosion rocked a bus carrying Israeli tourists at an airport in Bulgaria, killing at least four people. NBCNews.com's Dara brown reports.
Borisov said that the bomber's DNA and fingerprints had not matched anything held on file by Bulgaria or by partner spy agencies.

He suggested that the attacker, whose bomb was concealed in his backpack, may have entered Bulgaria on a plane from the European Union's "Schengen" passport-free travel zone.
"We do not know his identity, but it is known when he has arrived, the presumed flight, where he came from. It could turn out that he entered Bulgaria from a Schengen member country," Borisov said.
Israel's military chief insisted Tuesday that Iran and Hezbollah were involved and vowed that Israel would respond to the attack.
"We will have to find a way to respond to this attack, and not just a one-off," Lt. Gen. Benny Gantz was quoted as telling the Israeli parliament's foreign affairs and defense committee. "We will know how to do it judiciously. Ultimately, the response will come."
His comments were relayed by a meeting participant who discussed contents from the closed session on condition of anonymity. Iran has denied the accusations.
Borisov said that Bulgaria -- a member of both the European Union and NATO -- would not say who it thought was responsible for the attack until the investigation was complete.
Brennan said the U.S. has been working with Bulgaria on the investigation.
"Bulgaria will continue to have the full support of the United States in the weeks and months ahead," Brennan said.

Sounds like Israeli terrorism.
The Israeli killing their own to try and pin it on someone else?
You have them confused with radical Muslims. But then you know that. You just wanted to be the first to throw out a troll line, and congratulations... you got a bite.
You sound confused. Oh I cought a troll, Too small, I'll throw you back.
Wow! The anti-Israel crowd has just entered kindergarten. Lovely.
Dave-sunny so.cal
I can't decide whether you are a troll or an elite Iranian Republican Guard, whose duty it is to create spin in major public blogs. Either way your comments are transparent and poorly constructed.
Sounds like Mossad for sure. Ragheads do it differently.
Sounds like Dave and Max took a weekend course at a hezbollah or hamas training center.With their diplomas ads a stipend they are sent outtyo infiltrate places like newsvine.But if I was hezbollah or hamas I´d recall them for future training.You need to be a little more subtle.Israel has a great deal of experince with Verbal terrorists who use the BIG LIE. They are treated as flies that ar buzzing around their ears.and can be brushed off.An Islamic terrorist group is behind these murderes of Israeli and Bulgarians...Iran,hezbollah.hamas.talebans alquiada ..,they´re all made of the same cloth.Stay strong Bulgaria and let the investigation point fingers where it will.Foreign Islamic terrorists?.Local Islamic terrorists? Stay strong Bulgaria. Billions of people in the world support you! They too know what Isalmic terrorists have done in their countries!
The Zionists were willing to sacrifice their own people for political gains from day one. http://www.jewsagainstzionism.com/antisemitism/nazisupport.cfm/
Using an old Jewish concept, those Jews Against Zionism are now called Wicked Sons.
And yet, anti-Zionist crowd in Israel gets to have their party, hold their protest and no one is slaughtering them.
Compare that to how any Arab state treats those who disagrees with the government.
Can anyone spell M O S S A D?
If we were playing the game Jeopardy the question to the answer would be "Who will get even for this terrorist act"? And the answer would be "What is the Mossad". Oh, a conspiracy? Do you think?
Israel will stop at nothing to justify waging war on Iran. That country is so corrupt and evil that its a wonder that they can hold a straight face while saying "we're God's chosen people", which in itself is based upon the writings of a man in the Tora and later included in the christian bible verbatim, without question. Israel already controls our banking system, gold and diamond wealth, and kills their own people it seems.
Your comments are a good indication as to were you are on the "social scale"-----it is called "a social statement!!"
If they haven't by now, they will wait for some other stooge to do it for them. Not mentioning any names.
You have such a pretty face, Guess...it must be hard for you, when you are required to hide your face under a sheet.
Guess who?? Ingrid 11 the invincible..daughter of the hung nazi guard at Nuremburg.No you seem too young..Hezbollah suicide bomber who´s still alive after a botched attempt and now living in Iran.Who knows? Or bitten by Dracula you have no choice but to suck the blood of newsvine writers.Anyway please go to the newvine rocky horror show site.There you will find nazis and islamic terrorists ...
My old Victorian Grandmother had it right when she said "the only thing you can expect from a 'pig' is a grunt"
Sounds like the Iranians have been reading the same books that the KGB used.
Of course it was a muslim attack, what other group is cowardly and low enough to bomb and kill innocent youth? Only muslims eagerly kill and maim innocents...now the question is how will Israel retaliate? We all know the only language muslims understand is violence, so I'd guess Israel will wisely figure some kind of fair retaliation. Maybe something like for each Israeli, kill 100 muslims...aw, that's maybe not quite the ratio, more correctly should be 1 Israeli equals 200 muslims, or something close to that.
The guy who shot those people at the cinema was he a muslim.
Jack should be euthanized.
I see this time you are not even trying to push claims or make arguments, but stick to meaningless insults. Figures, that's so much easier.
Why is it whenever someone wants so stick a Jew in the oven, you are there with your mouth watering.
How is the weather in Iran ?
Are they paying you well ?
He was not unlike yourself; insane.
Yea,george zimmerman is a muslim too.
Jack was asking about groups...not deranged individuals.
Iranians aren't the only people who hate Israel. Chances are no one will ever know who carried out the attack except for the ones who did it and those who directed it. Israel will perform some type of retaliation even without any evidence. The drums of war are beating and bets are being placed. It's alot like the hype leading up to a big boxing match.
People in every country in the world hate Israel. Even Israeli people are starting to hate their country. Many people are self-immolating in protest.
Veni, I hate to be the one to break this to you, but surveys have shown that most Americans support Israel...including a survey right here on MSNBC, which can hardly be called pro-Zionist. And as for Israelis immolating themselves...funny that I have never heard about it.
Cassandra, a guy set himself on fire last week (he died 2 days ago) and another self immolated 2 days ago. Crawl out from under your rock and read the news before opening your mouth.
And you really should stop calling for other posters to be murdered.
Anyway, I looked up those self-immolations in Israel. They were not in protest against Israel's policies towards the Arabs, but rather about its lack of anti-poverty programs.
oh, and stephen burke who runs nbc universal, owner of this website, (he was formerly comcast coo) is an israel loving zionist.
whoa- when did i call for posters to be murdered? proof or it didn't happen sweetheart. my post history is there for all to see and to disprove that statement.
You just SAID that Jack should be euthanized.
Euthanasia isn't murder, it's being humanely put down to put them out of their own misery.
I'm pretty sure wishing death upon anyone goes against the code of conduct on here. Doesn't matter if it's done in a polite, humane way or not.
I am a red blooded American redneck that knows Israelies will let me live whatever way I chose. The Islamists want me dead if I don't subscribe to their brand of tyranny. The islamists also want the Jews dead for the same reason.
I know that the Jews have been persecuted for 4,000 years plus, attacked by pretty much everybody, but today, one group continues to attack them. The rest of the world has matured, but the Muslims still find the need to kill anything that they don't agree with. Including Americans, Europeans, Jews, artifacts, and each other because non of you can agree on anything but to kill.
dave-sunny so.cal, Jacques-2757417. Don Harris, guesswho22, VeniVidiVici, EchoJuliet: All anti-Semites.
2 of which I think are working for Iran. VeniVidiVici, EchoJuliet; Guess who I think I am talking about ?
All I can say to you is have fun with your virgins. There are no condoms in heaven, they have never been laid, and they are all male. Or, when you die, the lights just go out, and there is nothing else.
If you two were here with me, I would have no problem helping you into the next world.
Yeah, yeeehaw redneck. Crawl back into your hole and clean your guns.
Victor you´ve been standing on your head too long. Or you have a terminal case of moral dyslexia. where you see everything backwards and blame the victims not the brainwashed mass murdering terrorist killers.Next thing will be if you blame the dead people at the cinema for their own deaths.Give all of us a break and stop mucking up newsvine!
Veni Vidi Vici - that was what Julius Caesar said. You are no Caesar, neither are modern Moslem generals. For that reason you hate the Israelis.
It is sad that so many leftists and terrorist sympatizers readily show up on the vine to attack Israel - no intelligent debate - just anti semitic remarks. Yet, the same posters are nowhere to be found commenting on Syria murdering their own people in their homes and the streets. What a profound lack of morality.
What do you expect from vultures.
That's because Syria isn't murdering its own people. There are western paid and backed mercenaries perpetrating those atrocities. Read news from outside the US and you'd know that.
Then they must have had the hugest surge of immigration in the world, the record of all times.
Whenever I see comments like 10.2 above, there is always a "convenient " reason for them to stay in denial - no matter how far from being credible. Funny.
I think VeniVidiVici, and EchoJuliet are Whirling Dervishes or "entertainment boys" for gay Muslims, and want to suck my cock.
Fox, what I posted about the foreign mercenaries is pretty well known outside the confines of the western media. Even when they do report it, they only say 'foreign fighters pouring in from libya' but conveniently fail to mention who flew them there or who paid for it. The US is paying for it and media outlets in the states aren't going to trumpet the fact because they've been complicit in every war for the past 20+ years. Laugh at the facts all you want, just shows who's in denial when the truth is right there for those willing to see it.
So each and every rebel is foreign, no Syrians among them once or ever, while each and every citizen of Syria loves Assad, right?
I am starting to think that a lot of the really violent anti-Zionists and anti-Muslims are secret provocateurs, trying to arouse sympathy for the people they are attacking. I myself have responded to some of the wilder anti-Muslims by telling them about my fine Muslim doctors. It's hard to imagine the kind of wild charges that are made here.
Cassandra, you blow my mind on here every day. You, of all people, shouldn't be complaining about other people's 'wild charges'. You accused ME of urging the murders of posters on this site when I have never said such a thing. You also accused that guy Ralph of saying the Jews killed Jesus when he didn't say any such thing. You need to go see that nice Muslim doctor of yours for an evaluation.
I believe Cassandra she has always been a lady on the vine unlike other tramps who randomly show up here.
Thank you, Kate. We are very lucky to have you here. And we are also lucky that EJ said that Jack should be euthanized right here on this very site, shortly before insisting that he had never said he wanted to murder anybody. On the other hand, he is also lucky that Jack is not here, to say that he has never given anyone any reason to believe that he is in any misery and therefore wants to be killed. And as for RalphH denying that he ever said that the Jews killed Jesus...it is remotely possible that someone else is using the same name, since there is another Cassandra posting here, and I have occasionally had to respond that I should not be confused with her.
Then your definition of a 'lady' and mine differ greatly. A 'lady' doesn't fabricate or put words in the mouths of others as Cassandra has done. Our definitions of random are worlds apart as well, but at any rate, your opinion doesn't mean a squirt of pi$$ to me.
Anytime Cassandra! I know I don't always behave on the vine but hey nobody is perfect.
100% sure RalphH had a spin on the Jews killed Jesus (come on we're talking about Ralph!) just wish I could have read it since I'm sure it would have been a sizzler of a laugh.
I remember that post. It was just as idiotic as you imagine, but there were a lot of angry responses, that must be why Ralph hasn't tried that again.
But aaanyway- the Bulgarians are obviously right there was a conspiracy to murder Israeli tourists. This long haired dude did not act alone- IF he was the perpetrator to begin with. It would take at least several people to gather the necessary materials and pull this off. Israel has made enough enemies that it isn't necessarily the work of Iran or Hezbollah. They have also attacked and made life miserable for Lebanese, Egyptians and a host of others.
Well, anyone who blames their misery on Israel should be cursing the day they attacked Israel first, and before you know it, they might be cursing the day they planned this particular attack.
I think the main reason Israel is hated by these guys is because Israel hits right back while rest of the world is being more "peaceful" when provoked. Remember Munich retaliation? They kept killing all for twenty years. All the wars on Israel is humiliatingly lost. Like all crybabys and sissies, they whine and insult Israel for being so strong.
OK, you two- take your meds and calm down. Surely *someone* will pay for the attack, but as is customary with Israel, those on the receiving end won't necessarily be the perpetrators. The Pals have been paying for the actions of the Nazis since 1948.
The Pals have been paying for lobbing missiles at Israel and sending suicide bombers to buses, malls and restaurants.
The jews rationalizing aggression against Iran sound a lot like George W. Bush's run up to the Iraq invasion. WMD anyone?
Bob, Over 2,500 rocket attacks "by civilians", aimed at Israelites from Palestinian schools, hospitals, and apartments does not require an equal and opposite response ?
The damn targets were regular people going about their day.
How many bombs are going off in Palestinian streets triggered by Jews for the last 50 years ?
None, until Israel struck back at them with 50 years of anger. The Jews have been holding back like a mother-@!$%#er.
If this was happening to the United States, what do you think we would have done ?
Why Bob are so many Dems Nazi sympathizers ? What is wrong with your thought process ?
You need to calm down if you expect to be taken seriously. The Israelis- not Israelites (the Israelites haven't existed for 2000 years unless you want to count those crazy, homeless black racists who stand on street corners on NYC and spout nonsense about UFOs and them being the real Jews), have been killing Pals on the regular since before Israel's formation in '48. They kills women and children on a regular basis so do some unbiased research before opening your backwoods mouth. Calling Israel the peaceful victim is a big fat lie. You're so clueless I don't know why I bother to respond to backward @ss morons like you.
Actually, before 1948 the Jews and Arabs had been fighting each other for years.
According to jewish mythology, David killed 200 Palestinians and paid their foreskins to Saul for Saul's daughter.
That's someone else's mythology, not ours.
Although, it's understandable that anti-Israel crowd has to build their case on mythology, reality is not their friend.
Someone else? Who might that be?
While while Arabs excusing aggression against Israel is completely different thing. Indeed.
David ben Gurion was Polish. Menachem Begin and Golda Meir were Russian. Meir had the audacity to say "There is no such thing as a Palestinian."
In Poland, Ben Gurion was not considered polish. In Russia, Meir and Begin were not considered Russian. They all were considered jewish and were constantly told to go back to Israel where they came from. I lived through exact same experience in Russia.
And Meir was absolutely right, there really was not such thing as Palestinians at the time. Those who now call themselves Palestinians were calling themselves Egyptians, Jordanians, Lebanese or Syrians.
The Palestinians have a far better claim to being the Philistines than jews have to claim they are Israelites.
If you saw "Exodus," you were probably shocked to realize that the Jewish immigrants were called "Palestinians" and the people who now call Palestinians were "Arabs."
It probably was Mossad. They instantly came out and blamed it on Iran and Hezbollah. The dirty jews are most likely trying to justify a future offensive attack. Either that or pressure the US into doing its dirty work for them (AGAIN)... i reallly dislike Israel, if only Hitler would of finished the job....
Antonio, you need to crawl back under your rock, dude. Seriously. I may be angry at Israel but Hitler is not the name to invoke here.
WTF, is this news?
Or the jew media is making it news because victims are isrealis.
If iranians did it; I say they got balls.. What do you expect? You kill their scientists, thereaten them every freaking day with attackson their nuke facilities ete etc.. Are they gonna sit like pussy and wait to be whacked?
There are many other people could have done that..
many people who defend decency and equality fairness, freedom are a potential.. Which probably amounts to about 6 billion of the world population...
isreal, instead of bitching and moaning about iran, hizballa and other muslims committing crimes, it should look itself in the mirror and spit...
isreal needs lessons in decency, democracy, fairness. isreal needs to stop acting like a freaking brat.
how could anybody with the right mind can support isreal bitching about iran's nuke "ambititons"???? where they themselves possess many of them..
US should leave these a-holes alone in their fight with anybody in mideast....
Sure takes a lot of balls to blow up a few unarmed teenagers.
Behold islamist ethics.
Israel was God's chosen people along time ago, they were unfaithful and then went
to the nations of the gentiles. God is impartial and He desires people of all sorts to be
saved. He doesn't back countries, governments or people as they may claim. He
blesses those who proclaim His name and his will. Read the Bible it tells us what his
Name is and what his will is.
I think God "recalled" his choice (of isrealis) when he saw what jews have become..
Somewhere between genocide and Gulag we got sick and tired of being chosen people and decided to be just like everyone else.
So, form that day on, whenever we are attacked we strike back, just as anyone else would.
Takes them multiple highly-skilled individuals, a month of preparation, and a suicide attacker to put a bomb in the luggage compartment of a tourist bus and get a 20% kill ratio? One depressed American high school student can do more than that.
