The death toll from a building collapse in south-western Nigeria this week reached 35 on Thursday, a top emergency rescue official told dpa.
Some 17 more bodies were recovered from the rubble of the five-storey building that collapsed in Ikate in Lekki Lagos state on Tuesday, Michael Akindele, the general manager of the Lagos State Emergency Management Agency, said.
"We have about three excavators working to rescue whoever is left under the rubble," Akindele told dpa.
"We are working to ensure that the bodies are not mutilated during the rescue operation. The rescue operation has reached over 70 per cent."
The government may pull down a nearby five-storey building that is under construction as it has visible cracks on it, Akindele said, to avoid a similar situation.
The Lagos State Safety Commission and the State Building Control Agency have sealed more than 20 buildings in the community.
Buildings frequently collapse in Nigeria largely because of shoddy workmanship.
Some 116 people were killed in September 2014 after the collapse of a building used to house followers of popular evangelical preacher TB Joshua.
