Bombs planted on motor cycles in Pakistan's largest city Karachi have killed 25 people and injured nearly a hundred. A motor bike laden with explosives hit a bus carrying Shia Muslims to a religious procession killing 12 people. An hour later another motor cycle exploded outside the hospital where the victims of the first attack were being treated. Thirteen people were killed in that attack. A third bomb planted in a television set at the hospital was defused. Pakistani officials say at least one of the blasts was a suicide attack. <br/>
