A Nigerian flight that crashed in the country's largest city, killing all 153 people aboard, reported both of the aircraft's engines failed before it went down, the civil aviation chief has said.
"They declared mayday," Harold Demuren said. "The reason was that the two engines failed," he said, adding that the cause was not yet clear.
Meanwhile, Nigerian emergency services recovered more bodies today from the smouldering, ash-covered wreckage of the plane.
President Goodluck Jonathan declared three days of national mourning and ordered an investigation into the cause of Sunday's accident.
A McDonnell Douglas MD-83 flown by privately owned domestic carrier Dana Air crashed into the iron roof of an apartment block in the Lagos residential suburb of Agege.
Mr Jonathan's office said he was scheduled to visit the crash site on Monday afternoon.
"This is really a horrific moment for us here and we sympathise and give condolences to all the victims and families. (There are no) words to express our pain and grief," Lagos state governor Babatunde Fashola said at the crash site.
"It is saddening, it is simply too much."
The airline said on Sunday 147 people had perished, but in a list published overnight, there were also six crew members on board, taking the total to 153 killed. An unknown number of people may have been killed on the ground.
Oke Osanyintolu, head of the National Emergency Management Agency (NEMA) for Lagos state, told Reuters on the scene that 80 bodies had been pulled out by around 12.30pm.
A crane was helping clear the debris.
Search and rescue teams found what they believed to be the plane's black box flight recorder and handed it over to police, said Bankole Abayomi, director search and rescue for NEMA.
