The UN Human Rights Office condemned on Saturday the increasing frequency of Israeli Defense Forces (IDF) strikes on schools, where hundreds of thousands of forcibly displaced Palestinians have sought shelter, with the latest attacks killing dozens at a Gaza City school.

At around 4:30am during dawn prayer on Saturday, a mosque inside Al Tabaeen School was struck by the IDF “at least three times”, the UN rights office, OHCHR, in the Occupied Palestinian Territory said in a statement, adding that the attacks were “conducted with apparent disregard for the high rate of civilian fatalities”.

An initial report showed the strikes killed at least 93 Palestinians, including 11 children and six women.

This is at least the 21st strike on a school, each serving as a shelter, that the UN Human Rights Office has recorded since 4 July. These strikes have resulted in at least 274 fatalities, including women and children.

“For many, schools are the last resort to find some shelter and possible access to food and water,” according to the UN agency.

“Israel, as the occupying power, is obliged to provide the population it has forcibly displaced with basic humanitarian needs, including safe shelter,” the UN rights office said.
