A car bomb hit Libya's Foreign Ministry building in Benghazi at dawn Wednesday, exactly one year after an attack in the city killed the U.S. ambassador and three other Americans.
The blast blew out a side wall of the building, leaving office debris strewn across the street, but there were no reports of any fatalities.
It also damaged the Benghazi branch of the Libyan Central Bank, the Associated Press reported.
There were no claims of responsibility for the attack.
It comes exactly one year after al Qaeda-linked militants stormed the U.S. mission in Benghazi and a nearby U.S. building, killing U.S. Ambassador Chris Stevens and three other Americans.
Both Wednesday's bombing and last year's attack on the American consulate took place on the anniversary of the Sept. 11, 2001, attacks.
Car bombs and drive-by shootings since the end the civil war have killed security officials in Benghazi, the birthplace of the 2011 uprising that led to the overthrow of dictator Moammar Ghadafi.
