Between Monday and Friday afternoon, 252 Palestinians were reported killed in Israeli attacks on the Gaza Strip and 753 were injured, the UN Office for the Coordination of Humanitarian Affairs (OCHA) said in its latest situation report on the Palestinian territory, Al Jazeera reports.

Intense Israeli air strikes have targeted the Nuseirat, Bureij and Maghazi refugee camps in the central Gaza Strip, OCHA said.

A World Food Programme warehouse in Deir el-Balah was damaged on Thursday when an Israeli missile hit an adjoining flour mill, forcing the UN’s food agency to temporarily suspend operations at the site.

On the same day, the UN Children’s Fund (UNICEF) reported that nine out of 10 children in Gaza are experiencing severe food poverty, and are surviving on two or fewer food groups each day.

Military operations in Gaza “have significantly destabilized humanitarian aid flows, forcing UN and partners to reorganize the entire operation”, OCHA reports.
