Indian commandos killed two remaining gunmen at the historic Taj Mahal hotel in Mumbai Saturday, Police Chief Hasan Ghafoor said, ending four days of terror in the city.

"The Taj operation is over. The last two terrorist holed up there have been killed," Ghafoor told The Associated Press.

Commandos can be seen walking around in front of the hotel and fire trucks and ambulances pulled up to the front entrances for the first time.

During the fighting, smoke billowed out of the landmark hotel and gunfire and grenades exploding could be heard from the street.

The head of India's security forces told CNN-IBN that there could be more terrorists hiding in the city and that their operation was not over.  

Authorities wil now shift to who is behind the brazen attack that shocked the country and the world. It is believed that the militants were homegrown Muslim extremists related to a group known as the Indian Mujahedeen but experts say it is too early to be certain.

Earlier on Friday, Indian commandos found the bodies of six hostages, including a New York rabbi and his wife, after storming an ultra-orthodox Jewish centre in Mumbai Friday.

Some of the victims were found bound.

The death toll in the Mumbai terror attacks, which took place at 10 different sites starting Wednesday, has now surpassed 150.

Of the victims, 22 were foreigners, including two Canadians.

Early Friday night, Indian commandos finally got control of the Jewish centre after an intense standoff.

Two gunmen were also reported dead inside the centre but how they died is unknown.

"The Jewish centre has been cleared but now they're looking for any explosives that have been left behind," Y.P. Rajesh, a reporter with the Indian Express, told CTV Newsnet on Friday.

Late Friday, a spokesman for the Chabad Lubavitch movement, based in Brooklyn, N.Y., said that Rabbi Gavriel Noach Holtzberg and his wife, Rivka, were among those killed.

The couple's toddler son, Moshe Holtzberg, was smuggled out by an employee and is in the care of his grandparents.

Holtzberg was one of five Americans killed. It was not immediately clear if his wife had American citizenship.

A delegation from Israel's ZAKA emergency medical services unit was at the building to gather the dead.

Jewish law requires the burial of the entire body of a dead person, meaning the volunteers are responsible for gathering up all collectible pieces of flesh and blood.

R. Patil, a top official in Maharashtra state, said 370 people were injured in the various attacks.

As Friday evening set in, at least nine gunmen had been killed and one was arrested, Patil said.

Earlier Friday, about 20 Westerners, some of whom had Canadian flags on their luggage, emerged from the Oberoi hotel, another target in Wednesday's attacks.

Officials said commandos had killed the two last gunmen inside the Oberoi.

"The hotel is under our control," J.K. Dutt, director general of India's elite National Security Guard commando unit, told reporters.

He said 24 bodies had been found inside the hotel.

"We can see ambulances... lined up to carry bodies away," Rajesh said from his office across the street.

Meanwhile, one of the attackers has been captured and is being questioned by police.

Rajesh said officials now think the attacks may have been co-ordinated by the Pakistani militant group Lashkar-e-Toiba.

On Friday, India's foreign minister spoke out against Pakistan.

"According to preliminary information, some elements in Pakistan are responsible for Mumbai terror attacks," Pranab Mukherjee told reporters.
