Around 150 people have died in a fire at a petrol station in Ghana's capital, Accra, as per latest reports.
The fire on Wednesday night started as people in the city were trying to cope with two days of heavy rain, which has left many homeless and without power.
The flooding hampered rescue efforts and may have led to the fire, as per reports from Accra.
President John Dramani Mahama has announced three days of national mourning to begin on Monday.
It is thought that people were in the petrol station sheltering from the downpours when the fire broke out, our correspondent says. A further 25 people have died in the floods.
President Mahama visited the burnt-out petrol station and described the deaths as "catastrophic" and "almost unprecedented".
He vowed to take tough measures to stop people building on waterways, which appeared to have been a factor in the disaster.
"I think that the time has come for us to remove houses out of water and the public should understand that it is necessary to save everybody else," he said.
Following an emergency meeting of cabinet and security chiefs on how to tackle flooding, the government says it will release £9m ($14m) to help flood victims.
Schools were closed across the capital and children asked to stay at home.
