Two suicide bombers dressed in burqas blew themselves up Saturday in a camp for refugees fleeing military offensives in northwestern tribal region, killing 41 people and wounding 62, report said. The blasts occurred at a food distribution point, but there were conflicting reports whether the victims were lining up for food or being registered. The camp is sometimes used by foreign humanitarian groups, including the World Food Program, to deliver aid. The two suicide bombers struck six minutes apart at a camp in the Kacha Pukka area of Kohat, a tribally administered region close to the Afghan border. They were dressed in burqas, the all-encompassing veil worn by Muslim women in parts of Afghanistan and Pakistan, local police official Abdullah Khan said.
