Authorities have arrested a man they believe would have been a third bomber in twin suicide blasts at an army munitions factory that killed 67 people in one of Pakistan's deadliest terrorist attacks, police said Friday. The man was detained shortly after the blasts at two factory gates as workers streamed into the military's largest weapons-producing complex just west of the capital. Police also seized several other suspects and an explosives-laden jacket, according to local police official Mohammed Saeed. It was unclear whether the suspect was found with the explosives or why he apparently failed in his mission. Thursday's attacks in Wah, 20 miles west of Islamabad, also wounded 102 people.
