Pakistan says a series of explosions in the restive southwestern Baluchistan province has seriously wounded a soldier and damaged railway tracks and communications and power lines. Officials say two bomb blasts early Thursday in Mastung and Dera Ghazi Khan, located south and west of the provincial capital, Quetta, damaged railway tracks, causing train delays but no injuries. Another explosion destroyed a high voltage power line in Naushki area southwest of Quetta, disrupting electricity supplies throughout the area. And, in a remote Kohlu district, a rocket struck the tower of a telephone exchange, cutting phone lines to thousands of customers. Hours later, a soldier was seriously hurt in a land mine explosion while he was escorting a team of engineers to repair the tower.
