A suicide bomber set off explosives he was carrying outside the entrance of Pakistan's navy headquarters Wednesday, killing one security guard and wounding three others, police said.
The attacker, who appeared to be a teenager, detonated his explosives after he was stopped as he walked up to the iron gates at the heavily fortified complex at about 1:30 p.m. Islamabad police commissioner Fazil Asghar said one guard was killed after he asked the youth to remove his coat.
Security forces quickly cordoned off the area. The naval installation suffered no damage because it was a safe distance from the gate, officials said.
Pakistan has been hit by a series of bombings in recent months by Islamist militants.
