Flood and Ghana petrol station inferno kills about 150 in Accra,Ghana

Some 150 people have died in a fire at a petrol station in Ghana's capital, Accra, officials say.

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, the BBC's Sammy Darko 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, officials say.
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.

Survivor Yaw Aforve said he was sleeping in his car at the petrol station when he heard the fire

Bus conductor Yaw Aforve was sleeping in his vehicle which was parked at the petrol station when the fire started.
He said he jumped into the floodwaters and when he came up for air, the fire burnt his face.
"I was swept away by the water to the other side [of the road]," he added. "I saw so many people screaming and shouting."

The fire services say flooding contributed to the fire

The petrol station was totally destroyed by the fire

The flooding helped cause the fire, the Ghana fire service said.
The waters "caused the diesel and petrol to flow away from the gas station, and fire from a nearby house led to the explosion", spokesman Billy Anaglate said, the Associated Press news agency reports.

Two days of heavy rain has brought much of the city to its knees.
There are chaotic scenes with cars being carried away by the water and many roads blocked off.
Hundreds have been trapped in their offices and some have been forced to spend the night in their cars as traffic came to a standstill.
Parts of Accra have been left without power as electricity sub-stations have been damaged in the flooding, which is making the ongoing energy shortages even worse.

Blood was seen under the truck which was carrying away the dead bodies

Cars have been washed away and roads have been blocked by the flooding

Many homes have been flooded and people have been wandering around in their nightclothes after being forced to leave their beds.
One man told a local radio station that he had put his children on top of a wardrobe to save them from the water coming into his house.
Weather forecasters are saying that more rain is on its way.
