ISLAMABAD, Pakistan – Pakistan raised its nuclear ante Wednesday by saying it had conducted a successful test of an intermediate-range ballistic missile capable of carrying a nuclear warhead almost 600 miles, far enough to strike deep within India, its nuclear-armed neighbor.

The Shaheen-1 missile struck its intended target at sea, according to a statement from the Pakistani military.

The missile incorporates a series of technical improvements and has a longer range than its predecessors, the statement said.

Pakistan has an arsenal of at least 90 nuclear warheads and has been quickly increasing the range of its missiles, according to a report from the Congressional Research Service. 

The Bulletin of the Atomic Scientists says Pakistan has the world's fastest-growing nuclear stockpile.

Meanwhile, India has an estimated 100 nuclear weapons, according to the Arms Control Association, and tensions between the next-door neighbors, which have historically been high, have risen lately with a conflict over the disputed Kashmir territory.

In August 2012, Indian External Affairs Minister S.M. Krishna hinted at Pakistan when he mentioned “rampant proliferation in our extended neighborhood” during a speech in New Delhi.

“Nuclear weapons today are an integral part of our national security and will remain so,” Krishna said.

Pakistan, whose foreign ministry has said the country "is mindful of the need to avoid an arms race with India,” said Wednesday that the Shaheen-1 can accurately hit a target up to 560 miles away, compared with 430 miles for the previous version.

Senior military officers, along with scientists and engineers from the National Engineering and Scientific Commission, watched the launch, the government said.

Among those on hand was retired Lt. Gen. Khalid Ahmed Kidwai, director general of the country’s Strategic Plans Division, who was quoted by the government as saying the new version of the missile had “consolidated and strengthened Pakistan’s deterrence abilities manifold.”

Rescue workers carry a woman who was rescued from the rubble of a collapsed building in Mumbai, 36 hours after it fell to the ground "like a pack of cards."

MUMBAI -- The death toll from a collapsed building in India's financial center Mumbai rose to 72 on Saturday, as an injured woman trapped for 36 hours was freed from the rubble of the illegal and half-constructed building.

Rescue workers using cranes and bulldozers continued to search through the wreck of twisted steel and concrete after the seven-storey building collapsed "like a pack of cards" on Thursday evening, officials and witnesses said.

A shortage of cheap homes in Asia's third-largest economy has led to a rise in illegal construction by developers who use substandard materials and shoddy methods in order to offer rock-bottom rents to low-paid workers.

"The building collapsed like a pack of cards within three to four seconds," said Ramlal, a resident. "It just tilted a bit and collapsed," he said. Residents said laborers paying rent of around $5 a day had lived in the building.

The building, which was in a forested area in the city of Thane, had been made using poor materials and without proper approvals, said Sandeep Malvi, a spokesman for licensing authority the Thane Municipal Corporation.

He said 72 people had been killed and 36 injured had been admitted into local hospitals. "There may still be more bodies inside," Malvi added. "The rescue is still going on."

As the sun rose on Saturday, around 100 workers from the national disaster relief agency continued to use jackhammers and other equipment to cut through the pile of metal and concrete.

The woman dragged from the building on Saturday was found after workers heard her voice and used camera equipment to pinpoint her location under the rubble. A 10-month old infant was pulled from the debris on Friday.

Police said they were searching for the builders and would charge them with culpable homicide in connection with the disaster.

"Unauthorized constructions are a product of unavailability of affordable housing," said Lalit Kumar Jain, president of the Confederation of Real Estate Developers of India.

A sharp rise in property prices in densely populated Mumbai over the past five years has put housing out of reach for tens of thousands of lower earners, many of whom moved to the city in search of jobs, and who now sleep on the streets or in slums.

In 2012, India's urban housing shortage was estimated at nearly 19 million households, according to a report by the Ministry of Housing and Urban Poverty Alleviation.

Rescue workers look for trapped people after a residential building collapsed in Thane, Mumbai, India, Thursday, April 4, 2013.

At least 39 people were killed and dozens injured after an illegal, half-constructed building collapsed in seconds "like a pack of cards" on the outskirts of India's financial centre Mumbai, officials and witnesses said.

Rescue workers using cranes and bulldozers searched for survivors in the wreck of steel and concrete on Friday after the seven-storey building crumbled on Thursday night. Residents said laborers paying rent of around $5 a day had lived in it.

"The building collapsed like a pack of cards within three to four seconds," said Ramlal, a local resident. "It just tilted a bit and collapsed," he said. Read the full story.

The number of female tourists visiting India has fallen by more than a third since the gang-rape in which a 23-year-old student died, according to business leaders there.

Visitor numbers have dropped in all parts of the country, not just in New Delhi, where December’s attack took place, the Associated Chambers of Commerce and Industry of India (Assocham) said Monday.

The brutal assault was shocking even to a nation inured to sexual crimes against women, and thousands of protesters took to the streets in the weeks that followed to demand tougher action.

Four days later, a British woman in Agra jumped from a second-floor hotel room when she feared the manager was trying to break in, while in another case a Swiss man was held at gunpoint while his wife was gang-raped in Madhya Pradesh.

 “From December 2012 onwards the inflows of women foreign tourists to the country have gone down by 35 percent and the overall tourism being affected by 25 percent,” said Assocham’s secretary general, DS Rawat, in a press release.

Tour operators have reported that canceled bookings -- “especially from women” -- were mostly from the U.S., Britain, Canada and Australia, Rawat said.

He said the string of high-profile sex crimes “raised concerns about the safety of female travelers to the country,” adding that the cases attracted “international attention.”

He called on his country to strengthen security at major tourist spots, warning that India’s unsavory reputation could inflict “long-term” damage on its $17 billion annual tourism revenues.

About 6.6 million international tourists visited India last year, India’s tourism ministry estimates.

In the Dec. 16 attack, police say the gang lured the 23-year-old victim onto a bus in New Delhi, where they repeatedly raped and assaulted her with a metal bar before throwing her bleeding onto a highway. She died of internal injuries two weeks later.

Reuters reports — Two militants hiding automatic rifles and grenades in cricket equipment opened fire on a paramilitary camp on the Indian side of Kashmir on Wednesday, killing five Indian personnel and wounding five, police said.

The militants were killed in a gunfight at the Central Reserve Police Force (CRPF) base just outside the restive city of Srinagar, which has been under curfew for much of the last few weeks following protests and clashes with police.

Local media reports said that Hizbul Mujahideen, the bitterly disputed region's largest militant group, had claimed responsibility for the attack, in which three civilians were also wounded.

Police said the gunmen approached the camp by mingling with children playing cricket in a nearby field, hiding their weapons in the cricket gear they were carrying. Once at the camp, they shot a sentry dead and then fired indiscriminately into the base. Read the full story.

Media representatives surround an ambulance as it leaves the main entrance of Tihar Jail in New Delhi on Monday.

NEW DELHI -- The alleged ringleader in the gang-rape and death of a young Indian woman in December hanged himself in jail on Monday, officials said, a dramatic twist in a case that has provoked outrage across India.

Ram Singh's lawyer said his client had been composed and calm when he spoke to him on Friday and that there were other inmates in his cell in New Delhi's Tihar jail, raising questions about whether it was a suicide and how it could have gone unnoticed by staff in India's highest security prison.

The lawyer and a prison official said Singh had not been on suicide watch.

Police have described Singh as the ringleader of five men and a juvenile on trial for the December 16 attack on the 23-year-old trainee physiotherapist on a bus in the Indian capital. Singh was driving the bus.

All six accused have pleaded not guilty to rape and murder.

The assault triggered nationwide protests, a toughening of rape laws and an intense debate about rampant crime against women in India.

Tihar prison authorities ordered a magisterial inquiry after Singh was found hanging in his cell at around 5 a.m. (7 p.m. ET Sunday), prison spokesman Sunil Gupta said.

Singh's lawyer, V.K. Anand, told Reuters that his client did not appear to be distressed when he spoke to him on Friday.

"I believe he was satisfied with the way the trial was proceeding because we had a very strong case against the prosecution's claims," he said.

"This is not suicide, this is something else. I know he had a few complaints of jail authorities torturing him, but nothing that would make him take his own life. We can't rule out foul play. Nothing is adding up," he said.

The mother of Ram Singh cries as she speaks to journalists inside the family's home in New Delhi on Monday.

Anand has previously always denied that his client was being maltreated in prison. He did not elaborate on the "torture".

Singh had been kept in a cell with other inmates, he said.

A former director of the jail, Kiran Bedi, said Singh should have been kept isolated from the main prison population.

The trial of the five adult men started last month while the juvenile's trial began last week. Ram Singh's brother Mukesh Singh, gym assistant Vinay Sharma, bus cleaner Akshay Kumar Singh and fruit vendor Pawan Kumar are the other men on trial.

Under Indian law, the juvenile cannot be named.

The attack generated headlines around the world, but the case has since largely disappeared from public view, in large part because authorities have barred reporting on the trial, which was due to resume in a fast-track court on Monday.

Police allege the six attacked the woman and a male companion on the bus as the couple returned home after watching a movie on December 16. The woman was repeatedly raped and tortured with a metal bar. The couple were also severely beaten before being thrown onto a road.

The woman died of internal injuries in a Singapore hospital two weeks later.

The police report used to charge the accused draws a picture of Ram Singh as the ringleader. On the night of December 16, the accused gathered at his house for dinner, where he came up with the plan of taking the bus out to look for a victim to rape, the report said.

The police say they found him sitting in the blood-stained school bus, wearing a bloodied T-shirt, the morning after the crime. A DNA test revealed that the blood belonged to the rape victim, the report said.

Protesters near the Indian parliament Thursday complain that a new sexual violence law is inadequate. Their signs call for the removal of the deputy chairman of the parliament's upper house, P.J. Kurien, who is facing rape allegations.

NEW DELHI -- Police were searching villages in western India on Friday for suspects in the rape and killing of three young sisters, as Indians still angry over the fatal gang rape of a woman on a New Delhi bus in December face another heinous sexual attack.

The bodies of the sisters — ages 7, 9 and 11 — were found Feb. 16 in a village well in Bhandara district in Maharashtra after they had gone missing from school two days earlier, said police officer Abhinav Deshmukh. The area is more than 600 miles south of New Delhi, the capital.

The victims' mother said police did not take the case seriously and did nothing for several days until villagers held protests.

Deshmukh said Friday that 10 teams of 30 investigators were working on the case and that he was confident they would find the killers soon.

Police first dismissed the deaths as accidental, the Press Trust of India news agency reported. The girls' mother accused police of a shoddy investigation and said they did nothing for two days. Enraged villagers forced shops to close, burned tires and blocked a national highway passing in the area for hours earlier this week, demanding justice.

Police eventually registered a case of rape and murder after a post-mortem of the girls found that they had been sexually abused and brutally killed, PTI said.

One police officer has been suspended for not acting promptly, Indian Heavy Industries Minister Praful Patel, who represents Bhandara district in Parliament, said Thursday.

Cabinet Minister Manish Tewari called the killings a "very, very heinous assault" and said Prime Minister Manmohan Singh was sending 1 million rupees ($18,300) to the girls' family.

The case has horrified Indians two months after they were outraged by the gang rape and killing of a young woman on a moving New Delhi bus.

The gang rape sparked nationwide protests about India's treatment of women and spurred the government to hurry through a new package of laws to protect them.

The gang rape victim and her male friend, who also was badly beaten up in the attack, were dumped naked on the roadside, and the woman died from her injuries two weeks later in a Singapore hospital. Five men are being tried on rape and murder charges in that case, while a sixth, who is underage, is in juvenile court.

A new law enacted by the government has increased the prison sentences for rape from the existing seven to 10 years to a maximum of 20 years. It also provides for the death penalty in extreme cases of rape that result in death or leave the victim in a coma.

HYDERABAD, India -- A pair of bombs exploded Thursday evening in a crowded shopping area in the southern Indian city of Hyderabad, killing at least 11 people and wounding 50 more in the worst bombing in the country in more than a year, officials said.

The blasts occurred about two minutes apart outside a movie theater and a bus station, police said. Storefronts were shattered and television footage showed the wounded being rushed to hospitals.

"This is a dastardly attack, the guilty will not go unpunished," Prime Minister Manmohan Singh said. He appealed to the public to remain calm.

The bombs were attached to two bicycles about 150 meters (500 feet) apart in the district of Dilsukh Nagar, Home Minister Sushilkumar Shinde said. The district is a usually crowded shopping area near a residential neighborhood.

Eight people died in one explosion and three in the other, Shinde told reporters in the Indian capital of New Delhi.

Mahesh Kumar, a 21-year-old student, was heading home from a tutoring class when a bomb went off.

"I heard a huge sound and something hit me, I fell down, and somebody brought me to the hospital," said Kumar, who suffered shrapnel wounds.

Hyderabad, a city of 10 million, is a hub of India's information technology industry and has a mixed population of Muslims and Hindus.

An injured person is attended to at a hospital after a bomb blast in Hyderabad, India, on Feb. 21. A pair of bombs exploded Thursday evening in a crowded shopping area in the southern Indian city of Hyderabad, killing several people and wounding many in the worst bombing in the country in more than a year, officials said.

The explosions Thursday were the first major bomb attack to hit India since a September 2011 blast outside the High Court in New Delhi killed 13 people. The government has been heavily criticized for its failure to arrest the masterminds behind previous bombings.

Home Secretary R.K. Singh said officials from the National Investigation Agency and commandos of the National Security Guards were leaving New Delhi for Hyderabad.

India has been in a state of alert since Mohammed Afzal Guru, a Kashmiri, was hanged in a New Delhi jail nearly two weeks ago. Guru had been convicted of involvement in a 2001 attack on India's Parliament that killed 14 people, including five gunmen.

Many in Indian-ruled Kashmir believe Guru did not receive a fair trial, and the secrecy with which the execution was carried out fueled anger in a region where anti-India sentiment runs deep.
