Gunmen in the Nigerian state of Bauchi have abducted at least six foreign construction workers, in the biggest kidnapping in northern Nigeria in recent times.

A security guard at the Lebanese-owned construction company compound was also shot dead.

No-one has admitted the abductions but the Islamist militant group, Boko Haram, has staged a series of attacks in northern Nigeria.

The BBC's Tomi Oladipo reports from Lagos.
