Pakistan's military spokesman said on Friday the death toll in a train hijacking in the country's southwestern mountains had risen to 31 and he repeated accusations that neighbouring India and Afghanistan backed the militants who carried it out.

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.

Pakistan's army says it has freed more than 300 hostages from a passenger train seized by militants in Balochistan province on Tuesday. The military spokesperson said 33 militants were killed during the operation.
