This heartbreaking footage shows the true sorrow of Aleppo as a grief-stricken father watches the moment his son's dead body was pulled from the rubble.
The shocking footage appears to show the man fighting to hold on to the boy in the besieged al-Shaar neighborhood.
The footage shows civil defence workers carrying the body down from a building thought to have been damaged in an air strike.
The man screams in anguish, pulling the body from a worker and clutching it to his chest. The man has to be restrained as the body is taken and carried away.
The World Health Organisation and Red Cross called on Tuesday for dozens of sick and wounded people in the embattled eastern part of Aleppo to be evacuated through safe corridors for treatment.
