The courthouse bomber set off his explosive device at 1:20 p.m. (1120 GMT) as the police tried to search him and stop him from entering the building, state television cited the Damascus police chief as saying.

Syrian state television broadcast footage from inside the courthouse showing blood splattered on a floor littered with papers, a shoe and broken tiles and stones. Images from a hospital showed a man in a suit on a stretcher with blood on his clothes.
