Police say gunmen have abducted two European contract workers in Nigeria's northwest where such kidnappings are rare.

The Kebbi state police chief said the gunmen kidnapped an Italian and a Briton who had been working for an construction company Thursday night in the state capital of Birnin-Kebbi.

Adamu Hassan said Saturday there had not been a request for ransom.

Kidnappings are unusual in Nigeria's northwest — far removed from the country's southern delta where oil worker abductions had been frequent until recently.

However, Birnin-Kebbi is about 165 miles (265 kilometers) from the capital of neighboring Niger, where two French hostages were kidnapped in January.
