Indian commandos say the nearly three-day attack on Mumbai, India that killed three New Yorkers and about 200 others ended Saturday, after the last remaining gunmen holed up at the city's luxury Taj Mahal hotel were killed.

President George Bush held an hour-long teleconference at Camp David Saturday morning with Secretary of State Condoleezza Rice and the U.S. ambassador to India to discuss the terror attacks in India's financial capital.

Upon returning from Camp David, Bush pledged the full support of the Untied States to India, and condemned the attacks as an "assault on human dignity."

"As the people of the world's largest democracy recover from these attacks, they can count on the world's oldest democracy to stand by their side," said Bush, who said that President-elect Barack Obama was also being kept abreast of the situation.

Saturday morning, flames and smoke engulfed the landmark Taj hotel as Indian forces ended the siege in a hail of gunfire. Commandos then swept the hotel looking for survivors and booby traps left by the militants.

Explosions continued to rock the hotel as soldiers blasted open doors and set off explosives found on the gunmen.

About 200 people were killed and 300 were injured, but officials are worried the death toll may rise.

The U.S. Embassy says six Americans were among the foreigners killed.

Rabbi Gavriel Holtzberg and his wife Rivka and Rabbi Leibish Teitelbaum died at a Jewish center that served as the Mumbai headquarters for the ultra-orthodox Chabad-Lubavitch movement.

Gavriel Holtzberg, 29, grew up in Crown Heights and moved with his wife to Mumbai in 2003 to run the center.

Teitelbaum was a Brooklyn native who worked in Mumbai as a kosher food supervisor.

Leaders of the Chabad-Lubavitch movement held a prayer service before the beginning of the Sabbath.

Movement leaders say the Holtzbergs' young son was rescued by an employee and is now in the custody of his grandparents.

"This news is fresh and the wound is raw,” said Rabbi Yehuda Krinsky of the Chabad-Lubavitch movement in a press conference yesterday. “Words are inadequate to express our outrage and deep pain at this tragic act of cold-blooded murder."

"It's a terrible, terrible tragedy,” said Crown Heights resident Menachem Frietfertig. “It's really a tragedy for all mankind, not just the family, not just the Jewish people."

Senator Hillary Clinton, who reportedly could accept the incoming Secretary of State post as early as this week, issued a statement Saturday expressing her condolences.

The junior senator also condemned the deaths of two New Yorkers, saying, "There could be no sharper a reminder, nor a more poignant call to action, than the brutal and heinous violence visited upon the Nariman House and the Holtzberg family, living and working in Mumbai on a mission of peace, scholarship and spiritual guidance."

The NYPD is stepping up its presence at large hotels, Jewish centers and synagogues around the city in response to the Mumbai attacks.

Police were seen outside the Lubavitcher headquarters during last night's Sabbath.

Police Commissioner Ray Kelly said officers are paying close attention to what's going on overseas.

"We monitor world events on a daily basis and make adjustments accordingly on how we police this city," said Kelly. "And that of course includes our transit system, our financial services district, it includes landmarks and all of our neighborhoods."

The dead Americans also include Alan Scherr, 58, and his 13-year-old daughter Naomi, who were killed at the Oberoi Hotel cafe. They were traveling with a Virginia-based holistic group.

Germans, Canadians, Israelis and nationals from Britain, Italy, Japan, China, Thailand, Australia and Singapore were also killed.

Friday, Indian forces took control of the luxury Oberoi hotel, which was also attacked by militants. Dozens of people were rescued from the Oberoi and the last two gunmen were killed.

Indian officials say they believe just 10 gunmen carried out Wednesday's attack on 10 locations, since nine attackers were killed and one was captured and is now being questioned.

Although Indian officials are pointing fingers at rival Pakistan, Pakistani leaders insist their country was not involved in the attacks and are promising to help investigate.

"I stand with the people of India. I stand with the leadership of India. I am sorry that you are going through this," said Pakistani President Asif Ali Zardari.

"As far as the government of Pakistan is concerned, terrorism is terrorism," said Pakistani Foreign Minister Shah Mahmood Qureshi.

A team of FBI agents was ordered to fly to India to help investigate.

Indian security officers believe many of the gunmen may have invaded the city by sea.
