wA would-be suicide bomber shot himself dead Thursday when mourners confronted him at the funeral of a Pakistani police officer recently killed by militants, police said. The bomber panicked and ran when people at the funeral in the northwestern Batkhela area grew suspicious of him, said Aziz Khan, a local police official. It was unclear if the man had tried to detonate the explosives-filled vest found on his corpse. He was also carrying a hand grenade, Khan said. The funeral was for a senior police officer killed along with four colleagues when militants fired rockets at their vehicles in the nearby Dir region on Wednesday.
