ISLAMABAD, Pakistan (CNN) -- One person was killed and 11 others were wounded Wednesday when a suicide attacker blew himself up outside the entrance of the local naval headquarters in Pakistan's capital, a senior government official said.
The suicide bomber detonated explosives he was hiding under his coat when security officials stopped him at the entrance to the headquarters, said Captain Mobeen Ashraf Bajwa.
A security officer was killed, Bajwa said. Seven navy employees and four civilians were wounded, he said.
The attack occurred about 1:35 p.m. local time (3:35 a.m. ET).
It was the first suicide attack in Islamabad since a bomber blew himself up inside the offices of the United Nations World Food Program on October 5.
The naval headquarters is home to Pakistan's chief of naval staff and other senior navy officials. The families of navy officials also live there.
The headquarters is on a major road that goes through the heart of Islamabad and is protected by heavy security.
