That’s what witnesses say is behind the deaths of at least 98 people in Sierra Leone after a fuel tanker exploded in the capital of Freetown. The tanker collided with a truck on a highway as it was entering a petrol station to deliver its fuel. The drivers tried to warn those nearby to stay away from the leaking fuel, but reports say motorbike-taxi riders nearby started collecting the leaking fuel, causing a traffic jam. That led to a bus and vehicles on the road, nearby shops and market stalls going up in flames. “It’s a terrible, terrible accident,” said Brima Bureh Sesay, the head of the nation’s National Disaster Management Agency, and the government has declared it a national disaster.
