The international community has condemned the bomb attacks Tuesday that killed more than 160 people on commuter trains in the Indian city of Mumbai.
British Prime Minister Tony Blair called the attacks "brutal and shameful." He said his country stands united with India through shared values and a shared determination to defeat terrorism in all its forms.
U.S. Secretary of State Condoleezza Rice said those responsible for the bombings should be quickly brought to justice. She said the U.S. will stand with India in the war on terror.
Canadian Foreign Minister Peter MacKay said the attacks are another awful reminder of the determination of terrorists who use murder as a tool to advance their political ends.
And in neighboring Pakistan, President Pervez Musharraf and Prime Minister Shaukat Aziz called the attacks a "despicable act of terrorism."
In New York City, authorities announced an increase in patrols and bag searches in the city's vast subway system. The city's police department said the move is precautionary and there have been no specific threats. Last week, the FBI said it foiled a plot by al-Qaida militants to bomb one of the tunnels that links New York City with New Jersey.
A U.S. State Department spokesman, Sean McCormack said the U.S. has offered assistance to India.
