LAGOS (Reuters) - Gunmen attacked the vehicles of two German staff of a construction company in southwest Nigeria's Ogun state, shooting one dead and kidnapping the other, a senior security source told Reuters on Monday.

The attack on the cars carrying staff of Julius Berger Nigeria, which did not have escorts, occurred on Friday, the source said. Ogun state lies just outside Nigeria's coastal commercial capital of Lagos.

Ogun state police were not immediately available for comment. When contacted, the company declined to confirm the details but said only that it was working for the swift release of the hostage.
