Rescuers in Cameroon have reportedly found the black box from the Kenya Airways Boeing 737-800, which crashed in the south of the country on Saturday.
The twin-jet aircraft came down shortly after taking off in heavy rain from Douala on its way to Nairobi. All 114 people on board were killed.
Officials hope the retrieval of the black box will uncover the cause of the crash.
Ignatius Sana Juma, Cameroon's civil aviation director general, said: "We found the flight data recorder. We still need to recover the cockpit voice recorder."
A Cameroonian official in charge of the recovery effort said he had surveyed the entire site and no-one had survived.
"There are no chances of finding any [survivors] under the circumstances," Luc Ndjodo said.
"There is a crater filled with water and a clearing, then buried in the mud there are scattered plane parts and debris."
The aircraft was just six months old and part of a new fleet bought by Kenya Airways.
Kenya Airways has opened a crisis management centre at Embakasi – the site of the Kenyan capital’s airport.
