Unidentified attackers bombed a local government office in Somalia, killing two guards near the remote Kenyan border, officials said on Wednesday. Nine other people were wounded in several blasts that struck the building late on Tuesday in Belet Hawa, Ahmed Mohamed Barkus, a local Somali government official told Reuters by telephone. Belet Hawa lies just across the border from Kenya. The identity of the attackers was unclear, Barkus said
