Nearly 350 hostages were rescued at the end of a deadly standoff between Pakistan’s military and armed militants who hijacked a train in the southwestern Pakistani province of Balochistan, a security source told CNN Wednesday.

Hostages freed after a day-long ordeal following a BLA militant attack on a Pakistan train recalled crouching on the floor for hours before their release.

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.
