A previously unknown Muslim group with a name suggesting origins inside India claimed responsibility for the attack, but Indian officials said the sole surviving gunman was from Pakistan and pointed a finger of blame at their neighbor and rival.
Islamabad denied involvement and promised to help in the investigation. A team of FBI agents also was on its way to India to lend assistance.
Some 295 people also were wounded in the violence that started when heavily armed assailants attacked 10 sites across Mumbai on Wednesday night. At least 20 soldiers and police were among the dead.
Orange flames and black smoke engulfed the landmark 565-room Taj Mahal hotel after dawn Saturday as Indian forces ended the siege there in a hail of gunfire, just hours after elite commandos stormed a Jewish center and found at least eight hostages dead.
"There were three terrorists, we have killed them," said J.K. Dutt, director general of India's elite National Security Guard commando unit.
Later, adoring crowds surrounded six buses carrying weary, unshaven commandos, shaking their hands and giving them flowers. The commandos, dressed in black fatigues, said they had been ordered not to talk about the operation, but said they had not slept since the ordeal began. One sat sipping a bottle of water and holding a pink rose.
With the end of one of the most brazen terror attacks in India's history, attention turned from the military operation to questions of who was behind the attack and the heavy toll on human life.
The bodies of New York Rabbi Gavriel Noach Holtzberg and his wife, Rivkah, were found at the Jewish center. Their son, Moshe, who turned 2 on Saturday, was scooped up by an employee Thursday as she fled the building. Two Israelis and another American were also killed in the house, said Rabbi Zalman Schmotkin, a spokesman for the Chabad Lubavitch movement, which ran the center.
In Jerusalem, Israeli Foreign Ministry spokesman Yigal Palmor said eight bodies had been discovered in the Jewish center and that officials were investigating the possibility of there being a ninth.
Among the foreigners killed in the attacks were six Americans, according to the U.S. Embassy. The dead also included Germans, Canadians, Israelis and nationals from Britain, Italy, Japan, China, Thailand, Australia and Singapore.
By Saturday morning the death toll was at 195, the deadliest attack in India since 1993 serial bombings in Mumbai killed 257 people. But officials said the toll from the three days of carnage was likely to rise as more bodies were brought out of the hotels.
"There is a limit a city can take. This is a very, very different kind of fear. It will be some time before things get back to normal," said Ayesha Dar, a 33-year-old homemaker.
Indians began cremating their dead, many of them security force members killed fighting the gunmen. In the southern city of Bangalore, black clad commandos formed an honor guard for the flag-draped coffin of Maj. Sandeep Unnikrishnan, who was killed in the fighting at the Taj Mahal hotel.
"He gave up his own life to save the others," Dutt said from Mumbai.
A group called Deccan Mujahideen, which alludes to a region in southern India traditionally ruled by Muslim kings, claimed responsibility for the attack, but Indian officials pointed the finger at neighboring Pakistan.
On Saturday, officials said they believed that just 10 gunmen had taken part in the attack. "Nine were killed and one was captured," Maharshta state Chief Minister Vilasrao Deshmukh told reporters. "We are interrogating him."
Deshmukh's deputy, R.R. Patil, identified the gunman as a Pakistani national, Mohammad Ajmal Qasam.
The gunmen had sophisticated equipment and used "GPS, mobile and satellite phones to communicate," Patil said. "They were constantly in touch with a foreign country," he said, refusing to give further details.
