LAGOS, Nigeria — A passenger plane slammed into an apartment building in Nigeria's largest city shortly after takeoff Sunday. Firefighters pulled at least one body from the heavily damaged building and searched for survivors.

Casualty figures were not yet known, said Lagos state emergency manager EMI Oke-Osanyinpolu. It was unclear how many people were on board the plane or in the building, located just north of the airport. The Dana Air flight had taken off from the airport and was bound for Abuja, Nigeria's capital in the interior of Africa's most populous country, said Harold Denuren, head of the Nigerian Civil Aviation Authority. The plane went down in clear and sunny weather.

At the crash site, an Associated Press reporter saw parts of the plane's seat signs scattered around. The rest of the plane was cratered into the apartment building. Firefighters tried to put out the smoldering flames of a jet engine and carried at least one corpse from the building that continued to crumble. Thousands of people looked on.
