Dozens were also injured in the strike, said an official, Medhat Abbas, adding: “There is no water to extinguish the fire. There is nothing. This is a massacre” CAIRO: At least 28 Palestinians including children were killed on Thursday in an Israeli strike on a shelter in the northern Gaza Strip, a Gaza health ministry official said, while Israel said the attack targeted tens of militants at the site. Dozens were also injured in the strike, said the official, Medhat Abbas, adding: “There is no water to extinguish the fire. There is nothing. This is a massacre.” “Civilians and children are being killed, burned under fire,” said Abbas. The Israeli military said in a statement the strike targeted militants from Hamas and Islamic Jihad groups, who operated from within the Abu Hussein School in Jabalia that had been serving as a shelter for displaced people. It said dozens of militants were present inside the compound when the strike took place, and provided the names of at least 12 of them, which Reuters could not immediately verify. The military said it took precautions to mitigate harm to civilians and accused Hamas of using them as human shields — a practice Hamas denies. Hamas said in a statement that allegations there were fighters at the school were “nothing but lies,” adding this was “a systematic policy of the enemy to justify its crime.” The Hamas-run Gaza government media office put the number of dead at the school at 28. It said 160 people were wounded in the attack. Earlier on Thursday, Palestinian health officials said at least 11 Palestinians were killed in two separate Israeli strikes in Gaza City, while several others were killed in central and southern Gaza areas. Footage circulated by Palestinian media of the Abu Hussein School and which Reuters couldn’t immediately verify, showed smoke coming from tents that caught fire, as many displaced people evacuated casualties including children to ambulances. Residents of Jabalia, in northern Gaza, said Israeli forces blew up clusters of houses firing from the air, from tanks and by placing bombs in buildings then detonating them remotely. The area has been a focus for the Israeli military for the past two weeks, which says it is trying to stop Hamas fighters from regrouping for more attacks. Residents said Israeli forces had effectively isolated Beit Hanoun, Jabalia, and Beit Lahiya in the far north of the enclave from Gaza City, blocking movement except for those families heeding evacuation orders and leaving the three towns. “We have written our death notes, and we are not leaving Jabalia,” one resident told Reuters via a chat app. “The occupation (Israel) is punishing us for not leaving our houses in the early days of the war, and we are not going now either. They are blowing up houses, and roads, and are starving us but we die once and we don’t lose our pride,” the father of four said, refusing to give his name, fearing Israeli reprisal. The Israeli military said on Thursday that it seized many weapons in the area, some of which were stashed in a school, and that its forces have killed dozens of militants in airstrikes and combat at close quarters, as troops try to root out Hamas forces operating in the rubble. Northern Gaza, which had been home to well over half the territory’s 2.3 million people, was bombed to rubble in the first phase of Israel’s assault on the territory a year ago, after the Oct. 7 attacks on southern Israel by Hamas-led fighters, who killed 1,200 people and captured 250 hostages, according to Israeli tallies. More than 42,000 Palestinians have been killed in the Israel’s offensive so far, according to Gaza’s health authorities. The United States has told Israel that it must take steps to improve the humanitarian situation in northern Gaza in 30 days or face potential restrictions on military aid. Israeli Prime Minister Benjamin Netanyahu convened an emergency meeting on Wednesday to discuss expanding humanitarian aid to Gaza, officials said, with aid likely to increase soon.
