JERUSALEM (AP) — Israeli troops fired a mortar shell over the ceasefire line into a Palestinian residential area in the Gaza Strip, in the latest incident to rock the tenuous ceasefire with Hamas. Health officials said at least 10 people were wounded, and the army said it was investigating.
The military said the mortar was fired during an operation in the area of the “Yellow Line,” which was drawn in the ceasefire agreement and divides the Israeli-held majority of Gaza from the rest of the territory.
The military did not say what troops were doing or whether they had crossed the line. It said the mortar had veered from its intended target, which it did not specify.
Fadel Naeem, director of Al-Ahli Hospital, said the hospital received 10 people wounded in the strike on central Gaza City, some critically.
It was not the first time since the ceasefire took effect on Oct. 10 that Israeli fire has caused Palestinian casualties outside the Yellow Line. Palestinian health officials have reported over 370 deaths from Israeli fire since the truce.
Israel has said it has opened fire in response to Hamas violations, and says most of those killed have been Hamas militants. But an Israeli military official, speaking on condition of anonymity in line with military protocol, said the army is aware of a number of incidents where civilians were killed, including young children and a family traveling in a van.
Palestinians say civilians have been killed in some cases because the line is poorly marked. Israeli troops have been laying down yellow blocks to delineate it, but in some areas the blocks have not yet been placed.
The Israel-Hamas ceasefire is struggling to reach its next phase, with both sides accusing each other of violations. The first phase involved the exchange of hostages for Palestinian prisoners. The second is supposed to involve the deployment of an international stabilization force, a technocratic governing body for Gaza, the disarmament of Hamas and further Israeli troop withdrawals from the territory.
The remains of one hostage, Ran Gvili, are still in Gaza, and the militants appear to be struggling to find it. Israel is demanding the return of Gvili's remains before moving to the second phase.
Hamas is calling for more international pressure on Israel to open key border crossings, cease deadly strikes and allow more aid into the strip. Recently released Israeli military figures suggest it hasn’t met the ceasefire stipulation of allowing 600 trucks of aid into Gaza a day, though Israel disputes that finding.
Humanitarian groups say the lack of aid has had harsh effects on most of Gaza’s residents. Food remains scarce as the territory struggles to bounce back from famine, which affected parts of Gaza during the war.
The vast majority of Gaza’s 2 million people have been displaced. Most live in vast tent camps or among the shells of damaged buildings.
The initial Hamas-led Oct. 7, 2023, attack on southern Israel killed around 1,200 people and took 251 hostages. Almost all hostages or their remains have been returned in ceasefires or other deals.
Israel’s two-year campaign in Gaza has killed more than 70,660 Palestinians, roughly half of them women and children, according to the territory’s Health Ministry, which does not distinguish between militants and civilians in its count. The ministry, which operates under the Hamas-run government, is staffed by medical professionals and maintains detailed records viewed as generally reliable by the international community.
