Pakistan Prime Minister Shehbaz Sharif visited Balochistan province on Thursday, as dozens of people rescued from a train hijacked by separatist militants arrived in Quetta after security forces killed 33 attackers to end a day-long standoff.

Terrorists in explosive vests have reportedly threatened Pakistan train passengers' lives if officials refuse to release imprisoned militants.

Mehboob Hussain was riding the train home on Tuesday when the tracks under the front car exploded. In the depths of central Pakistan's Bolan Pass, a pocket of wilderness so remote that there is no internet or mobile network coverage, the nine-coach Jaffar Express ground to a halt. Then the bullets started flying.
