Dozens of people had sought shelter at the gas station and in nearby shops in central Accra to escape the torrential rains at the time of Wednesday night's blast. Flooding swept fuel being stored at the station into a nearby fire, triggering the explosion that also set ablaze neighboring buildings, officials said.
The West African nation will observe three days of mourning with flags flying at half-staff, and the government will allocate about USD 12 million for relief operations and to repair damaged infrastructure, President John Dramani Mahama told journalists yesterday night before heading into an emergency meeting.
TV footage earlier yesterday showed corpses being piled into the back of a pickup truck and other charred bodies trapped amid the debris. Floodwaters around the site hampered rescue and recovery efforts.
Officials at the nearby 37 Military Hospital said its morgue had reached capacity.

Mahama visited the blast site during the day, calling the death toll "catastrophic" and offering condolences to families of the victims.
The flooding "caused the diesel and petrol to flow away from the gas station and a fire from a nearby house led to the explosion," said Billy Anaglate, spokesman for Ghana's national fire service.
The deaths are likely to intensify criticism of the government's failure to improve the country's infrastructure. Though the downpours this week have been especially bad, heavy rains in June are not unusual yet drainage systems in Accra remain inadequate.
