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.

Pakistan army revealed that 18 out of 26 hostages killed in a Balochistan train ambush were army personnel. The Balochistan Liberation Army staged a dramatic siege, prompting a military intervention that rescued over 300 passengers and eliminated 33 terrorists.
