Oil tanker explosion in Sierra Leone kills dozens

An oil tanker has exploded in the West African nation of Sierra Leone, killing more than 90 people.

The explosion occurred after the fuel-laden tanker, more than 10 meters long, collided with a truck in the capital, Freetown, on Friday night.

The mayor of Freetown said on social media that 94 people have been confirmed dead and 92 others injured.

Video footage which was apparently taken immediately after the explosion shows smoke and flames emerging from spreading fire.

The cause of the accident has not been established.

Local media report that the blast occurred when a large crowd gathered to collect fuel leaking from the tanker after the collision.

The mayor said that she is deeply saddened to learn of the explosion, and that the video and photo footage making rounds on social media is harrowing.

She offered her sympathies to the families of the victims and vowed to provide necessary support.
