CNN) -- A car bomb exploded outside a Foreign Ministry building in the Libyan city of Benghazi Wednesday, state media said, on the anniversary of an assault on the U.S. Consulate there that killed four Americans, including Ambassador Christopher Stevens.

The blast did not cause any casualties but blew away large parts of the building's facade, said Col. Abdullah Al Zaydi, spokesman for the Joint Security Task Force in Benghazi, according to Libya's state news agency, LANA.

Zaydi said the explosion was very powerful and destroyed the vehicle used for the bombing, which contained a large quantity of explosives, the news agency said.

The blast also damaged a branch of the Central Bank of Libya and slightly injured one of its security guards, the bank said.
