Tony Blair condemned yesterday's "brutal and shameful" terrorist attacks on the Indian city of Mumbai in which 100 people were killed and another 300 injured.
The Prime Minister said Britain stood united with India after seven explosions rocked Mumbai's commuter rail network during the rush hour.
"I condemn utterly these brutal and shameful attacks," he said.
"There can never be any justification for terrorism. Our thoughts are with the victims and their families.
"We stand united with India as the world's largest democracy, through our shared values and our shared determination to defeat terrorism in all its forms," he added.
Indian Prime Minister Manmohan Singh called an emergency Cabinet meeting, and said that "terrorists" were behind the attacks.
Home Minister Shivraj Patil said authorities had "some" information an attack was coming, "but place and time was not known".
