Bombs planted by the roadside tore through two Pakistani navy buses taking employees to work on Tuesday, killing four people and wounding more than 50 others. The blasts took place roughly 15 minutes apart in different areas of Karachi, the country's biggest city, Navy Commander Salman Ali was quoted as saying by the Associated Press. Police said the bombs were concealed by the side of the road, and were presumably detonated by remote control. The victims included naval officers and employees of the force, said Ali, adding one of the dead was a female doctor.
