(CNN) – In every corridor, every corner of the Omar Hospital in Aleppo, there are scenes of horror. Decapitated bodies on the hospital’s floor, children with bloodied faces, screaming mothers searching for their families under the rubble — these were some of images that one medic described to CNN after a hospital in eastern Aleppo was attacked Saturday. “Whatever I say I will not be able to describe the horror I am seeing,” Aref al-Aref, who filmed the aftermath of the shelling, said.
