A still image taken from Israeli Defence Forces (IDF) video footage shows what they say is a small unidentified aircraft shot down in a mid-air interception after it crossed into southern Israel on Oct. 6, 2012.
The leader of the Lebanese militant Hezbollah group has claimed responsibility for launching the drone aircraft that entered Israeli airspace earlier this week.
The rare admission Thursday by Hassan Nasrallah raises regional tensions at a sensitive time when the group's backers, Syria and Iran, are under pressure.
Earlier Thursday, Israeli Prime Minister Benjamin Netanyahu accused Hezbollah of launching the drone.
The unmanned aircraft was shot down by Israel, but the infiltration marked a rare breach of Israel's airspace. Hezbollah had been the leading suspect because of its arsenal of sophisticated Iranian weapons and a history of trying to deploy similar aircraft.

Nasrallah said in a televised speech that the drone was Iranian-made and went down near the Dimona nuclear reactor in the Negev Desert, after flying some 25 miles into Israel.
"The drone flew over sensitive installations inside southern Palestine," he said in a televised speech.
Hezbollah does not recognize Israel.
"Today we are uncovering a small part of our capabilities, and we shall keep many more hidden," Nasrallah added. "It is our natural right to send other reconnaissance flights inside occupied Palestine ... This is not the first time and will not be the last. We can reach any place we want" inside Israel, he said.
With a formidable arsenal that rivals that of the Lebanese army, Hezbollah is already under pressure in Lebanon from rivals who accuse it of putting Lebanon at risk of getting sucked into regional turmoil. Confirmation that Hezbollah was behind the drone could produce further internal strain as it pursues its longstanding conflict with Israel.
Israel routinely sends F-16s over Lebanon, breaking the sound barrier over Beirut and other places as a show of strength.
Hezbollah, a powerful Shiite group committed to Israel's destruction, has long served as an Iranian proxy along Israel's northern border. The two sides fought a brutal monthlong war in mid-2006. Hundreds of people were killed, and Hezbollah fired several thousand rockets and missiles into Israel before the conflict ended in a stalemate.
Hezbollah has attempted to send unmanned aircraft into Israel on several occasions, dating back to 2004. Nasrallah has claimed that the group's pilotless aircraft were capable of carrying explosives and striking deep into Israel.
The last known attempt by Hezbollah to use a drone took place during the 2006 war, when Israel shot down an Iranian-made pilotless aircraft that entered its airspace.
Since the fighting ended, the sides have been locked in a covert battle against one another.
Touring southern Israel on Thursday, Israeli Prime Minister Benjamin Netanyahu praised efforts to prevent land infiltrations from Egypt. He mentioned that Israel has been equally successful "in the air, just like we thwarted the Hezbollah attempt last weekend," his first public statement blaming Hezbollah.
Israel says the drone was not carrying explosives and appeared to be on a reconnaissance mission.
During the televised speech, Nasrallah denied sending fighters into Syria to help Hezbollah's ally President Bashar Assad to quell the rebellion in Syria.
"We did not fight alongside the regime until now. The regime did not ask us to do so and also who says that doing so is in Lebanon's interest?" Nasrallah said.
Hezbollah's opponents have accused it of sending fighters into Syria. Last month, the U.S. Treasury sanctioned Nasrallah for helping Assad crush anti-government protests, as well as two other members for the group's "terrorist activities" in general.
