The International Committee of the Red Cross (ICRC) has said the humanitarian convoy was able to deliver medical supplies to Al Shifa hospital nonetheless.
Two trucks were damaged and a driver was lightly wounded, the organisation said.
It said the convoy included five trucks and two ICRC vehicles and was carrying “lifesaving medical supplies to health facilities including to Al Quds hospital of the Palestinian Red Crescent Society, when it was hit by fire.”
The group did not identify the source of the fire.
