At least 28 people, including children, have died in a wave of Israeli military strikes throughout the Gaza Strip, according to Gaza's civil defence agency.
A school sheltering displaced families was among the facilities struck, killing eight people including four children over the weekend, the agency said.
It comes as the UN issues a plea for Israel to cease its attacks in the vicinity of a hospital in Gaza's north.
The Israeli military claimed a Hamas command centre was inside the compound of the Musa bin Nusair school in Gaza City, and has not commented on reports of attacks by the hospital.
