Huge explosions at an arms depot that killed at least 146 people in Congo’s capital Brazzaville were caused by a short-circuit that led to a fire, government officials say.
They say some 1,500 people were hurt.
Rescuers are still searching for survivors amid fears that the death toll would rise further.
The force of the blasts was felt several miles away in the city of Kinshasa, across the border in the Democratic Republic of Congo.
The BBC’s Thomas Hubert, in Kinshasa, says residents of east Brazzaville fled when the blasts began.
He says the explosions started shortly after 08:00 local time (07:00 GMT) on Sunday and continued into the early afternoon, causing panic in both cities.
