The Balochistan Liberation Army claims it killed 6 security forces and seized a Pakistani passenger train carrying about 500 people in a remote, mountainous region.

The militants, Baloch ethnic fighters, said they would kill dozens of seized security personnel if the Pakistani government did not agree to a prisoner exchange.

The death toll from a militant hijacking of a train in Pakistan's southwestern mountains has risen to 31 soldiers, staff and civilians, the military said on Friday as it accused India and Afghanistan of backing the insurgents.

The train hijacking in south-western Pakistan represents a major escalation in the region’s long-running insurgency.

The BLA said they gave the Pakistan Army 48 hours to exchange prisoners of war, but since they did not heed their warning, they killed the hostages
