The explosion happened 200 kilometers west of Tanzania's capital Dar es Salaam
Fifty-seven people perished in Tanzania on Saturday when a fuel tanker exploded after overturning on a road west of the capital Dar Es Salaam, police said.
The disaster took place near the town of Morogoro, with police saying the blaze may have been sparked by a cigarette as people rushed to collect leaking fuel from the stricken truck.
"There was a huge blast which has so far killed at least 57 people," regional police chief Willbrod Mtafungwa told reporters,.
Witnesses said they saw the charred remains of a number of motorcycle taxis and trees scorched by the flames.
Mtafungwa said the dead were mainly drivers of the taxis known as "boda-boda" and local residents flocking to the scene for the fuel after the tanker crashed.
Police later announced the fire had been brought under control.
