Sudan; what us the back story?
Thanks Godzilla!
Basically, the opposing sides have been jockeying around for power for a number of years now. The RSF developed out of the Darfur wars and like many of the factions drew international support - in this case from radicals associated with iran with some Wagner backing thrown in. The Iranian angle is probably the most significant in that it would give them another African state on the Red Sea that could impact shipping that passes thru the Suez Canal as well as shipping destined for Israeli ports.
