Gunmen attacked a camp for a construction company in north Nigeria, killing a guard and kidnapping seven foreign workers including one from Britain, authorities told the Associated Press.
The attack happened on Saturday night in Jama'are, Bauchi, a region under attack by Islamic extremists, where gunmen first targeted a local prison, burning two police trucks, Bauchi state police spokesman Hassan Muhammed said.
The gunmen then attacked a workers camp for construction company Setraco where they shot dead a guard before kidnapping one British, one Greek, one Italian and four Lebanese citizens.
Britain's Foreign Office said it was looking into reports that a UK national had been kidnapped in Bauchi state.
