QUETTA, Pakistan: A bomb planted on the track killed at least one train passenger and wounded four others in Pakistan’s restive southwestern province of Balochistan on Tuesday, officials said. The improvised explosive device exploded as the Jaffar Express from Rawalpindi passed over it 180 kilometers (111 miles) east of Quetta, local security official Naseer Ullah told AFP. “A passenger was killed and four others were wounded and moved to hospital,” he said. A three-feet section of the track was destroyed by the bombing, which hit the second carriage. The injured were taken to hospital in the town of Sibbi 25 kilometers north of the blast site.
