Islamabad, Safar 17, 1434, Dec 30, 2012, SPA - At least 19 persons were killed when a bomb destroyed two buses in south-western Pakistan on Sunday, a senior administration official said. The blast occurred in Mastung district of Balochistan province, according to a report of DPA. "Nineteen bodies have been retrieved from the wreckage of buses," said Tufail Baloch, deputy commissioner of Mastung. "Up to 25 people, including four women, have been injured." Baloch said the buses were traveling under escort, adding that at least two security officers also sustained injuries in the explosion.
