Warning: This report by ITV News Correspondent Dan Rivers contains distressing images
The Beit Hanoun elementary school, which was being used as a shelter, had around 800 people - mostly women and children - inside when the attack took place at 2.30pm today.
UN spokesman Adnan Abu Hassna told ITV News that the Israeli military attacked the school, despite having received the exact co-ordinates of the facility.
But Israel neither admitted or denied responsibility for the attack.
Dan Rivers reported seeing dozens of children lying in "pools of blood" in a local hospital.
A six-month-old baby boy had to be treated for shrapnel wounds after the attack.
The strike came on another day of fierce fighting in the region, despite continued diplomatic pressure for a ceasefire.
More than 700 Palestinians - mostly civilians - have been killed in the 16-day conflict.
Israel has lost 32 soldiers in the violence.
