The US has sent an Federal Bureau of Investigation team to assist in the probe into the Mumbai attacks as President George W Bush pledged 'full support' to India in its efforts to unearth the plot behind the deadly terror strikes.
While a group of FBI agents were en route to India, a second group of investigators was on alert to join the first team if necessary.
"The FBI continues to monitor the situation in Mumbai and the Counterterrorism Division is reviewing all available information and intelligence," bureau spokesman Richard Kolko told The Washington Post.
Bush, who was in Camp David for the Thanksgiving holiday, held an hour-long video-teleconference with US diplomats in India and discussed the situation, the report said.
Among those participating were Secretary of State Condoleezza Rice, US ambassador to India David Mulford, Paul Folmsbee, the consul general at the US consulate in Mumbai and members of Bush's national security team.
Bush had on Saturday pledged 'full support' of the United States as India investigates the attacks, brings the guilty to justice and sustains its 'democratic way of life'.
"The killers struck this week are brutal and violent, but terror will not have the final word...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," the US President had said.
