Sudan's paramilitary Rapid Support Forces have executed at least 31 people, including children. That's according to the Sudan Doctors Network, which condemned the killings, calling them a war crime and a crime against humanity. RSF fighters accused the victims of links with the army. It happened in the Salha area southwest of Omdurman - that's near the capital Khartoum. The UN has repeatedly accused the group of carrying out summary executions and other atrocities.
