BAUCHI, Nigeria (Reuters) - Gunmen kidnapped seven foreigners and killed a security guard when they stormed the compound of Lebanese construction company Setraco in northern Nigeria's Bauchi state early on Sunday, the police said.

Among those abducted were a Briton, an Italian, a Greek and more than one Lebanese worker, including two women, local government chairman Adamu Aliyu and security sources said.

Northern Nigeria is plagued by attacks and kidnappings by Islamist groups. Al Qaeda aligned group Ansaru claimed the kidnap in December of a French national who is still missing.

Bauchi Police Chief Mohammed Ladan said the gunmen attacked a police station and a prison overnight before storming the construction firm's compound in Jama'are town.

"We repelled the attack on police station and the security men at the prison yard also repelled the attack, but they burnt two vehicles in Jama'are police station," Ladan said.

"They then attacked Setraco construction, killed a local security guard and they succeeded in kidnapping people."

The Italian foreign ministry confirmed one of its nationals was taken in the raid. A spokesman for the British Embassy in Abuja said it was investigating.
