KADUNA, Nigeria (AP) — The Nigerian air force says one of its aircraft has crashed into a residential house in Kaduna state killing all four crew and three passengers.

Commodore Dele Alonge, air force spokesman, said the Dornier-228 aircraft had taken off from Kaduna Military Airfield Saturday morning bound for the country's capital, Abuja, when it crashed in a house in the Ribadu area.

Alonge said bodies of those in the plane have been recovered and firefighters are at the crash site trying to prevent the fire from spreading.

Earlier this month, a helicopter belonging to Bristow, a Houston, Texas-based firm that charters helicopters to oil and gas rigs, traveling from an oil rig crashed into a lagoon in Nigeria's largest city, Lagos, killing four people.
