In short, the footage of the riflemen and the drone strikes is new and was clearly filmed in Sudan. However, more work is needed to verify the allegiance of the armed men through open sources.
One example is of this location where a drone strike hit on camera. We matched it to this location on Google Maps (15.661269, 32.489888), in the Wad Nubawi district of Omdurman.
We geolocated later footage showing four men lying behind a rifle to the same location as the one individual sniper who is also seen in the group footage
Weapons expert @CalibreObscura told Bellingcat that the precise model of the firearm could likely not be determined, partly due to the mesh and partly due to the quality of the footage.
At this stage, our team can't confirm whether this soldier is Ukrainian. The camouflage pattern on his uniform resembles the commercially available Multicam pattern. This pattern has reportedly been used by multiple militaries.
The video is essentially several pieces of footage stitched together. It starts with a man in camouflage, shooting a sniper rifle from the top of a mountain just west of Omdurman. Bellingcat was able to geolocate his position. (15.708352, 32.426962)
Babel UA claimed their sources in Ukrainian intelligence said the men were Ukrainians fighting the Rapid Support Forces (RSF) who were backed by the Russians via Private Military Company Wagner.
On October 6, 2023 a video started circulating of alleged Ukrainian fighters in Sudan. It was subsequently shared by Telegram channels such as .@truexanewsua and Ukrainian sites such as babel.ua. https://twitter.com/clashreport/status/1710241167751671844
