At least six foreign workers have been seized and a security guard shot dead by gunmen who attacked a construction company site in northern Nigeria, officials say.
One of the workers seized was Italian, one was Greek and two others Lebanese.
But UK officials could not confirm a report that another was British.
No-one has admitted the abductions but the Islamist militant group, Boko Haram, has staged a series of attacks in northern Nigeria.
A security guard was killed as the attackers targeted the workers’ camp at Jama’are in Bauchi state.
