Nigerian police say gunmen have kidnapped at least six people, including at some foreigners from a construction site in the country's north after a failed attack on a prison.
Police say the gunmen shot and killed a security guard at the Lebanese-owned company's site at the town of Jama'are in Nigeria's Bauchi State before fleeing with the workers.
There has been no immediate claim of responsibility for the kidnappings.
Authorities say the suspects initially tried to overtake a prison in the area, but were turned back.
The Associated Press reports that a local official says foreigners from Britain, Italy, Greece and Lebanon are among those kidnapped overnight. The report has not been confirmed.
