Warning: This story contains graphic descriptions of executions.

Fighters from the paramilitary Rapid Support Forces (RSF) have executed a number of unarmed people after capturing the Sudanese city of el-Fasher, new videos analysed by BBC Verify show.

The RSF, which has engaged in a brutal war with the Sudanese Armed Forces (SAF) for more than two years, seized a key military base in the city over the weekend after an extended siege.

Several videos have since emerged showing men wearing military fatigues and some with what appear to be RSF patches carrying out extreme acts of violence around el-Fasher. The UN's Sudan coordinator stated they received credible reports of summary executions in the city.

BBC Verify has approached the RSF for comment. Imran Abdullah, an adviser to the paramilitary, denied the group's fighters were targeting civilians.

Since the start of the conflict in 2023, more than 150,000 people have died and around 12 million have fled their homes.

Denise Brown, the UN's Sudan coordinator, reported executions of unarmed men specifically since the RSF took control of el-Fasher, highlighting the war crimes under the Geneva Convention.

Most videos reviewed by BBC Verify could not be precisely geolocated, but one showed an unarmed man shot at a university building in el-Fasher, further emphasizing the tragedy occurring in the region.

The RSF continues to engage in violent conflict as they seek control in Sudan, leading to widespread fear and chaos.
