(CNN) -- A grenade exploded outside the Egyptian Consulate in the eastern Libyan city of Benghazi on Saturday evening, Libyan state media reported.
There were no casualties, but the Libyan state news agency LANA reported some material damage.
Unidentified assailants threw a type of locally-made grenade at the consulate before they fled, Benghazi Joint Security Room spokesman Col. Abdullah Al-Zaidi said, according to LANA.
The blast partially damaged the outer perimeter wall of the consulate and some vehicles parked nearby, the official said.
Calls to the Egyptian Embassy in Tripoli and the consulate in Benghazi were immediately unsuccessful.
