In a follow-up communication Sunday afternoon, a spokesman at the Ministry of Aviation, James Odaudu, said the "aircraft reported engine failure at time 10:39 and crashed landed on the final approach path of Abuja Runway 22 at time 10:48UTC."

Odaudu said firefighters have been deployed to the scene to put out a raging blaze that had engulfed the airplane.

An aviation worker who asked not to be named -- citing lack of official clearance to talk to the press -- told CNN that he witnessed the crash.

"The crash occurred not very far from the runway. The pilot had tried returning to the runway after taking off," he said.

The worker said the pilot swerved the plane to its crash site which is in a desolate area. He said the aircraft narrowly avoided warehouses and makeshift settlements around the Nnamdi Azikwe International airport.
