Video verified by Reuters showed bloodied bodies strewn around the market. It also showed fires burning and people being carried from the wreckage of stores and fruit stalls.
People can be heard crying and screaming in the footage, while others pray for those who were killed. One man is heard saying “People are dying wholesale”.
The video also shows armed men in the headwraps typically worn by RSF soldiers on motorcycles.
An activist from Kabkabiya said that, while there were typically a few soldiers in the market and other parts of the town, the vast majority of those present were civilians.
He said 87 bodies had been identified, but that some were too charred or mutilated to identify.

Images circulating on social media not verified by Reuters showed shrouded bodies on the street amid vehicle wreckage.
