The White House on Monday condemned the train blast attacks which killed at least 66 passengers in northern India and expressed grief over the loss of lives.

"We express our deepest sorrow for this tragedy and extend condolences to the families of the victims.

"We appreciate the leadership of Indian Prime Minister ( Manmohan) Singh and Pakistani President (Pervez) Musharraf, and condemn those who seek to undermine the progress in relations between the two countries," White House spokesman David Almacy said.

In addition to the killed, more than 20 people were seriously wounded, some of them Pakistani nationals in the explosions aboard the train which runs from India to Pakistan.
