The official number of people who have died since a building collapsed in Nigeria’s commercial capital Lagos earlier this week has risen to 20.
Lagos state health commissioner Jide Idris released the number in a statement but did not disclose how many children are among the dead.
The four-storey building contained a school which had more than 100 pupils, a rescue official told the BBC.
The building had been identified as “distressed” and listed for demolition, Lagos building officials said.
Authorities in Nigeria have started demolishing buildings near the site of the four-storey structure that collapsed on Wednesday in Lagos.
Local reports suggest that dozens of houses have been served with a demolition notice.
Omotayo Fakolujo, from the Lagos State Building Control Agency told the BBC that more than 100 buildings will be demolished on Lagos Island.
He added that a minimum of three will be demolished per day.
He also denied allegations that owners of marked buildings had paid bribes to avoid demolition
