QUETTA, Pakistan (Reuters) -Dozens of people rescued from a train hijacked by separatist militants in southwestern Pakistan arrived on Thursday in the city of Quetta, hours after security forces killed all 33 attackers to end a day-long standoff.

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.
