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.

After more than a day of fighting with separatist militants who hijacked a train carrying hundreds of passengers, Pakistan’s army said it had brought the insurgent attack to an end, but that 21 passengers and four paramilitary personnel had been killed.
