An electrical short is to blame for the fire that killed 27 children at a Quranic boarding school east of Monrovia two weeks ago, Liberia’s National Fire Service has confirmed.

Alex Dixon, Fire Service Director, said that an investigation into the fire also determined that a motorcycle full of gasoline was parked inside the school building when the fire broke out.

He did not confirm if the gas tank of the motorcycle exploded.

According to AP, the fire gutted a dormitory and school building while students slept around midnight on September 17.

Some students escaped, though it’s unclear how many.

The Liberian government has promised to rebuild the school as words of sympathy and material assistance continue to pour in for bereaved families.
