An Indian court on Wednesday acquitted four Hindu men accused of bombing a train between India and Pakistan in 2007 that killed 68 people, mostly Pakistanis, citing a lack of evidence, defense lawyers said.

Pakistan's acting foreign secretary described the ruling as a "travesty of justice."

The ruling comes weeks after a sharp escalation in tensions between India and Pakistan after a suicide car bomb in Kashmir killed 40 Indian paramilitary police. Pakistan-based militant group Jaish-e-Mohammed claimed responsibility for the attack.
