MUMBAI, India — Indian commandos killed the last remaining gunmen holed up at a luxury Mumbai hotel Saturday, ending a 60-hour rampage that killed 195 people in India's financial capital, as authorities shifted their focus to who was behind the attacks.

A previously unknown Muslim group claimed responsibility for the attack, which killed 18 foreigners including six Americans. Indian officials said the sole surviving gunman was from Pakistan and pointed a finger of blame at their neighbor. Islamabad denied involvement and promised to help in the investigation. A team of FBI agents was on its way to India to lend assistance.

Some 295 people also were wounded in the violence that started when at least a dozen 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 nine 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.

Some hotel guests were still believed to be in their rooms. "They are still scared, so even when we request them to come out and identify ourselves, they are naturally afraid," Dutt said.

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.

Among the foreigners killed 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. Officials said the three day toll was likely to rise as more bodies are brought out of the hotels.
