The U.S. Embassy in Nigeria's capital says there were gunshots fired near its offices, though no one was injured.
A statement from the embassy Monday said it "believed there were shots fired" and that police arrested two people afterward. Abuja police spokesman Jimoh Moshood said he had no information about any shooting in the area, nor any knowledge of any arrests.
Security remains a concern in Nigeria as a radical Islamist sect known as Boko Haram continues a wave of killings across the nation's Muslim north. A suicide car bombing by the sect in August attacked the United Nations' headquarters in Abuja _ which sits on the same road as the embassy.
