All 117 passengers and crew of a commercial airliner which crashed on an internal flight in Nigeria on Saturday were killed, the government has said.
It is not yet known what caused the plane to crash soon after takeoff
There had initially been conflicting reports about whether anyone survived.
But officials at the scene said no-one could have survived the plane's impact, the cause of which remains unknown.
Senior officials, including an MP and a general, were said to be on the flight. The government has declared three days of national mourning from Monday.
President Olusegun Obasanjo urged all Nigerians to pray for the victims and their families.
The pilot of Bellview Airlines flight 210 sent a distress signal just after taking off from Lagos for the Nigerian capital, Abuja, in stormy weather at 2045 (1945 GMT) on Saturday.
The plane was first reported found on Sunday morning by a police helicopter search team near the rural town of Kishi, Oyo state, 400km (320 miles) from Lagos. It was suggested 50 people might have survived.
But officials later retracted statements about the plane's location and survivors after a TV crew said it had found the aircraft near the village of Lissa in Ogun state, about 50km (30 miles) from Lagos.
Images of mangled bodies, twisted chunks of metal and ripped luggage were broadcast.
The National Emergency Management Agency said on Sunday afternoon that the plane had crashed and burst into flames in swampland north of Lagos.
Spokesman Ibrahim Farinloye told AFP news agency that the plane hit the ground with such speed it was partly buried under ground. No-one on the plane would have lived after the initial impact, he said.
Nigerian Red Cross officials confirmed no sign of survivors had been found at the scene.
Hundreds of anxious relatives and friends of the 111 passengers and six crew have besieged the domestic terminal of Lagos airport seeking information.
