A passenger plane with about 150 people on board has crashed into buildings in a densely populated district of Nigeria's main city of Lagos.
Nigeria's Civil Aviation Authority said there were no survivors on board the Dana Air plane but the cause of the crash is not yet known.
Thousands of onlookers gathered at the crash site as rescue services searched the rubble for survivors.
President Goodluck Jonathan has declared three days of mourning.
The commercial aircraft was flying from the Nigerian capital, Abuja, to Lagos when it crashed and burst into flames.
