Dozens of people have been killed in a drone strike at a displacement shelter in el-Fasher, a besieged Sudanese city on the brink of collapse, activists said, BBC reported.

The resistance committee for el-Fasher, made up of local citizens and activists, said the paramilitary Rapid Support Forces (RSF) hit Dar al-Arqam camp, located within a university, with two drone strikes and eight artillery shells. The RSF has denied it carried out the strike.

"Children, women and the elderly were killed in cold blood, and many were completely burned," a statement from the group said. 

Eyewitnesses described scenes of panic as rescuers pulled bodies from the rubble, according to BBC.
