🧵1/6 After the El Fasher massacre, I identified a large UAE-aligned influence operation on X promoting the Rapid Support Forces (RSF). Around 19,000 accounts showed strong indicators of automation - bots marcowenjones.substack.com/p/i-found-19... #Sudan #Dysinfluence

A few months ago, we published our short doc on a military camp that can be linked to the RSF, about 80km south of Kufrah airport. This camp was already active in January this year, and still is until this day.

With CIR's Sudan Witness, I mapped these tracks and identified truck-sized objects and smoke plumes along this route from Kufrah far into Sudan, such as this one captured by Planet on 5 November, coming from a convoy allegedly hit by an airstrike.

Of these 384 reported strikes, 168 were corroborated by collecting and verifying user-generated content and analysis of satellite imagery. Munitions remnants identified in multiple cases can be linked to the SAF. More than 1700 civilian deaths were reported as a result of these strikes

Important example showing how synthetic aperture radar (SAR) and optical satellite data are complementary. Here are pairs of images used by Reuters to document gravesites in Sudan’s famine-stricken Zamzam camp. www.reuters.com/investigates... Imagery from Umbra (SAR) & Airbus (optical).
Four images showing fresh graves in cemeteries near the Zamzam refugee camp. The left column is two synthetic aperture radar images, which look like grainy black and white photos. On the right are two very high resolution true-color satellite images. Some graves are visible in both synthetic aperture radar and true-color imagery, others are more easily identified in one or the other. The two types combined help provide a more accurate picture of the total number of graves.
