At least 28 people, including children, were killed in a wave of Israeli military raids across the Gaza Strip, according to the Gaza Civil Defense Service.
The agency said that a school housing displaced families was among the facilities that were bombed, killing eight people, including four children, over the weekend.
This comes at a time when the United Nations issued a call to Israel to stop its attacks on the vicinity of a hospital in northern Gaza.
The Israeli military claimed that the Hamas command center was inside the Musa bin Nuseir school compound in Gaza City, and did not comment on reports of attacks by the hospital.
“Hamas is systematically violating international law,” the Israeli military said on social media, adding that Israel’s response would be to “act with force and determination against terrorist organizations.”
Gaza Civil Defense spokesman, Mahmoud Basal, told Agence France-Presse that the school had been converted into a shelter for Palestinians displaced by the war.
Abu, one of the displaced people who was staying in the school, told BBC Arabic that the attack occurred while he was sleeping.
He added: “We were sleeping peacefully, then suddenly we woke up to the sound of a very strong explosion.”
Another man, Mahmoud, said he was sleeping in a tent in the school yard when the attack occurred.
He told BBC Arabic: “Stones and shrapnel were flying, and the school walls fell on our heads.”
Pope Francis on Sunday condemned the Israeli attacks on Gaza for the second day in a row.
He expressed his pain at the thought of “such cruelty, shooting children, bombing schools and hospitals.”

The head of the World Health Organization, Dr. Tedros Adhanom Ghebreyesus, issued a call to the Israeli army to stop attacks in the vicinity of the hospital.
He said in a statement on social media that reports on Saturday night of “bombing near Kamal Adwan Hospital and the order to evacuate the hospital are deeply concerning.”
He added, “We call for an immediate ceasefire around the hospital and to protect patients and health workers.”
The hospital director also issued a statement in which he said that the Israeli forces were treating the hospital “as if we were a military facility.”
Dr. Hossam Abu Safia said: “Anyone who leaves the hospital is at risk of being targeted.”
He added that moving hospital operations would put patients at risk, and called for health workers to be allowed “to work without the threat of evacuation.”
Israel did not comment on the reports regarding the evacuation order.
The BBC has contacted the Israeli army for comment.
Palestinian groups involved in the fighting told the BBC that Ceasefire agreement 'closer than ever'.
