A suicide bomber blew himself up at a busy market in the Pakistani capital on Monday, killing at least one person in the first bombing in Islamabad in over a year and a half, police said. No group immediately claimed responsibility for the bombing, the Associated Press reported. The suicide bomber tried to enter a bank building in the market but was stopped by a security guard, said Islamabad police chief Wajid Durrani. The bomber then detonated his explosives, killing the guard and wounding four others, Durrani said. The blast ripped through the ground floor of the bank, scattering body parts and pieces of broken glass on the pavement outside.
