Horrifying videos and reported atrocities allegedly carried out by RSF militia in and around the Sudanese city of El Fasher demonstrate a “total disregard” for both protection of civilians and the Security Council’s resolution demanding an end to the civil war.

That’s according to the UN’s head of humanitarian operations in the country, Denise Brown, who told UN News after recently visiting the Darfur region before the fall of the city this week, that it’s proving hard to verify information from the stricken city due to a communications blackout.

She told Ezzat El-Ferri she feels a “huge sense” of tragedy and responsibility to continue providing UN relief services, adding that the atrocities must be documented so that “justice can be served.”
