Al Jazeera cameras caught tens of civilians and emergency medical personnel scrambling to rescue victims - mostly women and children - immediately after the deadly strike.
Hundreds of Palestinians were sheltering in the school as Israel continued deadly airstrikes and bombardments of residential buildings in the north of the Gaza Strip.
The strike against the school in Al-Saftawi came less than five hours after Israeli airstrikes killed 15 and injured 65 in the immediate vicinity of Al-Shifaa Medical Complex in Gaza City.
The director-general of hospitals in the Gaza Strip had told Al Jazeera the Israeli airstrikes targeted ambulances that were leaving Al-Shifaa to transport wounded to the Rafah border crossing in order to enter Egypt for treatment at Egyptian hospitals.
