At least 73 people are dead after an explosion at a petrol station in Ghana's capital, Accra.

A spokesman for the Ghana Fire Service says rescue crews are still recovering bodies at the scene.

There are fears the death toll could rise significantly.

The cause of the explosion is believed to be due to a fault caused by torrential rain.

Neighbours say many people had taken shelter at the station amid torrential rains and flooding.

President John Mahama has visited the scene and appealed for calm.
