An explosion at a petrol station in Ghana killed more than 250 people, according to local media reports.

The blast took place in Ghana's capital city of Accra near the Kwame Nkrumah Circle, where many people were taking shelter from the heavy rains.

According to Reuters, at least 150 people are feared dead.

However, local media outlet reported that more than 250 bodies have been found so far. 

Ghana's Daily Guide reported that more than 130 are feared dead in the inferno, and that the military hospital in the area has said it cannot take any more bodies. 

The accident is said to be linked to the torrential rains. Flood waters swept stored fuel towards a fire, leading to the explosion, according to reports.  

Eyewitnesses said that the blast occurred due to petrol spillage on the surface of the flooding water that caught fire, IANS reported, citing Xinhua news agency. 

Accra has faced flooding after heavy rains lashed the city. 

Ghana's President John Mahama announced a three-day national mourning following the disaster.
