The Islamist group Ansaru has claimed the kidnapping of seven foreigners, believed to include at least one Briton, in a deadly raid on a construction site in northern Nigeria, according to the Associated French Press.
In an email statement the group said it has "the custody of seven persons, which include Lebanese and their European counterparts working with Setraco."
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.
