Militants today struck Pakistan's Naval Headquarters in Islamabad with a teenage suicide bomber blowing himself up at the gate of the complex, killing a naval official and injuring three others. In the brazen attack, the bomber approached the naval headquarters complex on Margalla Road, and blew himself up on being challenged by the guards. The attack on the Naval headquarters comes nearly two months after Taliban militants targeted the Army General Headquarters in the garrison town of Rawalpindi leaving 22 people, including 11 security personnel, dead. The bomber was carrying heavy explosives wrapped around his body and he detonated it as the naval policemen tried to frisk him. No group claimed responsibility for the assault though the Pakistani Taliban has been blamed for a series of bombings and suicide attacks, many of them targeting the security forces.
