Khartoum, April 28 -- At least 31 civilians were killed by the paramilitary Rapid Support Forces (RSF) in Omdurman, north of the Sudanese capital Khartoum, volunteer groups reported on Sunday.

"An RSF force carried out a horrific massacre, executing 31 people from the Al-Salha area, including underage children, in the deadliest documented mass killing the area has ever witnessed," the Sudanese Doctors Network, a volunteer group, said in a statement.

"We consider this mass execution a war crime and a crime against humanity. We call on the international community to act urgently to save the remaining civilians and to open safe corridors to allow them to leave Al-Salha, which is home to thousands of unarmed civilians," it added.
