An Israeli air strike on a school building sheltering displaced Palestinians in Gaza City has killed dozens of people, Hamas-run authorities in the territory say.
A spokesman for the Israel Defense Forces (IDF) said al-Taba’een school "served as an active Hamas and Islamic Jihad military facility" with approximately 20 "militants" operating there.
More than 60 people were killed and 47 injured, the health ministry’s ambulance service said, quoted by the AP news agency.
Earlier, the Gaza civil defence agency - a rescue service - said at least 90 people were killed. The BBC cannot independently verify figures from either side.
Israel has attacked several such shelters in Gaza in the past few weeks.
According to the United Nations, 477 out of 564 school buildings in Gaza had been directly hit or damaged as of 6 July, with at least another 14 targeted since.
Al-Taba’een school housed more 1,000 people - having recently received dozens of displaced people from the town of Beit Hanoun, after the Israeli army ordered them to leave their homes.
The building also served as a mosque and the Israeli strike hit during dawn prayers, witnesses said.
Jaafar Taha, a student who lives near the school, told the BBC the sound of the bombing was followed by screaming and noise.
"'Save us, save us', they were screaming," he said.
"The scene was horrific. There were body parts everywhere and blood covering the walls."
Israel's military said it had "precisely struck Hamas terrorists operating within a Hamas command and control centre embedded in the al-Taba'een school".
A statement by IDF spokesman Lt Col Nadav Shoshani said that "based on Israeli intelligence, approximately 20 Hamas and Islamic Jihad militants, including senior commanders, were operating from the compound struck at the al-Tabaeen school, using it to carry out terrorist attacks".
The spokesman said the casualty figures released by Hamas officials "do not align with the information held by the IDF, the precise munitions used, and the accuracy of the strike".
Hamas described the attack as a "horrific crime and a dangerous escalation" in Israel's "war of extermination against the Palestinian people".
Fatah, Hamas's political Palestinian rival in the West Bank, said Israel's aim was "to exterminate Palestinians through a policy of cumulative killing".
The reported casualty figures for Saturday's early-morning attack are higher than in most such strikes.
But targeting school buildings has become a regular feature of IDF operations in recent weeks, apparently as part of what it says is an ongoing effort to destroy Hamas military infrastructure.
Since the beginning of July, more than a dozen schools have been hit, according to unofficial tallies, including at one point four in four days.
Each time, in nearly identical statements, the IDF says Hamas is hiding in the schools and using them as command centres to plan and carry out attacks, something Hamas denies.
Whatever the case, these buildings are where many displaced Gazans have sought shelter, and they are paying the highest price.
Many of the schools were run by the UN before the war, and the UN has strongly condemned the strikes.
It is not clear if this incident will impact struggling efforts to agree a ceasefire deal, which were set back by the assassination of the Hamas political leader Ismail Haniyeh in Iran.
But Egypt, one of the mediators involved in efforts to reach such a truce, said Israel’s “deliberate killing” of unarmed Palestinians showed that Israel lacked the political will to end the war.
Jordan said it was "an indication of the Israeli government’s efforts to obstruct and thwart these efforts".
Hamas-led gunmen killed about 1,200 people in an attack on Israel on 7 October, taking 251 others back to Gaza as hostages.
That attack triggered a massive Israeli military offensive on Gaza and the ongoing war.
More than 39,600 Palestinians have been killed in the Israeli campaign, according to Gaza's Hamas-run health ministry.
