Bomb Kills Pakistan Pilgrims

Violence rocked Pakistan early Sunday as militants killed 41 people in two separate incidents. Suicide bombers struck a bus convoy of Shiite pilgrims, killing 20 and injuring dozens more. Meanwhile in the north, 21 paramilitary soldiers who were being held by militants were executed. The brutal incidents are part of a surge in militant attacks in recent weeks. The U.S. has pressured Pakistan to crack down on such groups.
