At least 28 Palestinians have been killed by Israeli strikes overnight and from dawn on Sunday, with many of them during an attack on a school-turned-shelter for the displaced in Gaza City, according to the territory's civil defence.
Eight of those victims - including four children -, were killed in the attack on the Musa Bin Nusayr School that sheltered displaced families in Gaza City.
One of the deadly attacks occurred on the home belonging to the Abu Samra family in central Gaza's Deir el-Balah.
Attacks killing Palestinians also took place in Gaza's southern city of Rafah, medics said.
Israel has also been targeting the Kamal Adwan Hospital in Beit Lahia, northern Gaza, considered a lifeline for those injured in the Strip.
Hussam Abu Safiya, the director of Kamal Adwan Hospital, said on Sunday the army ordered staff to evacuate the hospital and move patients and injured people toward another hospital in the area.
Abu Safiya said the mission was "next to impossible" because the staff did not have ambulances to move the patients.
Experts say that the Israeli army's attacks aim to push the hospital out of service.
