An Israeli strike on a school sheltering the displaced in the Gaza Strip killed at least 27 people on Thursday, Palestinian medical officials said. The Israeli military said it targeted militants hiding among civilians, without providing evidence.

Israel has continued to strike at what it says are militant targets across the Palestinian enclave even as attention has shifted to its war against Hezbollah in Lebanon and rising tensions with Iran. The military launched a large-scale air and ground operation against Hamas in northern Gaza earlier this week.

In a separate development, the U.N. peacekeeping force in southern Lebanon said an Israeli tank fired on its headquarters in the town of Naqoura, hitting an observation tower and wounding two peacekeepers, who were hospitalized.

UNIFIL said in a statement that its headquarters and nearby positions “have been repeatedly hit.” It said the army also fired on a nearby bunker where peacekeepers were sheltering, damaging vehicles and a communication system. It said an Israeli drone was seen flying to the bunker's entrance.

Strike on shelter appears to have targeted Hamas-run police
The strike in the central Gaza city of Deir al-Balah killed 27 people, including a child and seven women, according to the Al-Aqsa Martyrs Hospital, where the bodies were brought. It said several other people were wounded.

An Associated Press reporter saw ambulances streaming into the hospital and counted the bodies, many of which arrived in pieces.

“We appeal to the world. We are dying!” one man screamed.

The Israeli military said it carried out a precise strike targeting a militant command and control center inside the school. Israel has repeatedly attacked schools that were turned into shelters in Gaza, accusing militants of hiding out in them.

Witnesses who spoke on condition of anonymity for security reasons said the strike occurred while school managers were meeting with representatives of an aid group in a room normally used by Hamas-run police who provide security. They said there were no police in the room at the time.

The Hamas-run government operated a civilian police force numbering in the tens of thousands. They largely vanished from the streets after the start of the war as Israel targeted them with airstrikes, but plainclothes Hamas security personnel still exert control over most areas.

Hamas has continued to launch attacks on Israeli forces and fire occasional rockets into Israel more than a year after its Oct. 7 attack ignited the war.

Hamas-led militants stormed into Israel and rampaged through army bases and farming communities in that attack, killing some 1,200 people, mostly civilians, and abducting around 250 others. They are still holding around 100 captives, a third of whom are believed to be dead.

Israel’s offensive has killed over 42,000 Palestinians, according to local health authorities, who do not say how many were fighters but say women and children make up more than half of the fatalities. The war has destroyed large areas of Gaza and displaced around 90% of its population of 2.3 million people, often multiple times.

UN peacekeepers caught in intensified fighting in Lebanon
The Hezbollah militant group in Lebanon began firing rockets into Israel on Oct. 8, 2023, in support of Hamas and the Palestinians, drawing Israeli airstrikes in retaliation.

The fighting steadily escalated, and eventually boiled over into all-out war in recent weeks, with Israel carrying out waves of heavy strikes across Lebanon and launching a ground invasion. Hezbollah has expanded its rocket fire to more populated areas deeper inside Israel, causing few casualties but disrupting daily life.

Iran supports Hamas, Hezbollah and other armed groups across the region that refer to themselves as the Axis of Resistance against Israel. Iran launched some 180 ballistic missiles at Israel last week in retaliation for the killing of top Hamas and Hezbollah militants.

Israeli Defense Minister Yoav Gallant said Wednesday that its response to the Iranian missile attack will be “lethal” and “surprising,” without providing further details, as Prime Minister Benjamin Netanyahu spoke with U.S. President Joe Biden.

The U.N. peacekeepers in Lebanon were tasked with patroling a buffer zone set up after the monthlong Israel-Hezbollah war in 2006.

Israel accuses Hezbollah of ignoring the U.N. resolution that ended the war and establishing militant infrastructure right along the border. It says the ground invasion, which has so far focused on a narrow strip along the border, is aimed at pushing the militants back so tens of thousands of Israelis can return to their homes.

Israel has warned people to evacuate from dozens of communities in southern Lebanon, many of which are outside the buffer zone.

Lebanon accuses Israel of violating other provisions of the U.N. resolution that ended the last war. It has said it will dispatch its armed forces to help U.N. peacekeepers control the border area and implement the U.N. resolution, but neither is capable of imposing anything on Hezbollah by force.
