CAIRO – A unit of the Hamas-run police force said it killed 12 members of an Israeli-backed militia after detaining them early Thursday in the Gaza Strip. Hours earlier, an Israel-supported aid group said Hamas attacked a bus carrying its Palestinian workers, killing at least five of them.

The militia, led by Yasser Abu Shabab, said its fighters had attacked Hamas and killed five militants but made no mention of its own casualties. It also accused Hamas of detaining and killing aid workers. It was not immediately possible to verify the competing claims or confirm the identities of those killed.

The Israeli military circulated the Gaza Humanitarian Foundation ‘s statement on its social media accounts but declined to provide its own account of what happened.

Aid initiative already marred by controversy and violence

The aid group’s operations in Gaza have already been marred by controversy and violence since they began last month, with scores of people killed in near-daily shootings as crowds headed toward the food distribution sites inside Israeli military zones. Witnesses have blamed the Israeli military, which has acknowledged firing only warning shots near people it said approached its forces in a suspicious manner.

Earlier this week, witnesses also said Abu Shabab militiamen had opened fire on people en route to a GHF aid hub, killing and wounding many.

The United Nations and major aid groups have rejected the Israeli and U.S.-backed initiative, accusing them of militarizing humanitarian aid at a time when experts say Gaza is at risk of famine because of Israel’s blockade and renewed military campaign.

Last week, Israel acknowledged it is supporting armed groups of Palestinians in what it says is a move to counter Hamas. Abu Shabab’s militia, which calls itself the Popular Forces, says it is guarding the food distribution points set up by the Israeli- and U.S.-backed Gaza Humanitarian Foundation in southern Gaza. Aid workers say it has a long history of looting U.N. trucks.

GHF has denied working with the Abu Shabab group.

‘They were aid workers’

In a statement released early Thursday, the foundation said Hamas had attacked a bus carrying more than two dozen “local Palestinians working side-by-side with the U.S. GHF team to deliver critical aid” near the southern city of Khan Younis.

“We condemn this heinous and deliberate attack in the strongest possible terms,” it said. “These were aid workers. Humanitarians. Fathers, brothers, sons, and friends, who were risking their lives everyday to help others.”

It did not identify the men or say whether they were armed at the time.

Israel and the United States say the new system is needed to prevent Hamas from siphoning off aid from the long-standing U.N.-run system, which is capable of delivering food, fuel and other humanitarian aid to all parts of Gaza. U.N. officials deny there has been any systematic diversion of aid by Hamas, but say they have struggled to deliver it because of Israeli restrictions and the breakdown of law and order in Gaza.

U.N. officials say the new system is unable to meet mounting needs, and that it allows Israel to use aid as a weapon by controlling who has access to it and by essentially forcing people to relocate to the aid sites, most of which are in the southernmost city of Rafah, now a mostly uninhabited military zone. Some fear this could be part of an Israeli plan to coerce Palestinians into leaving Gaza.

Hamas says it killed traitors

Hamas has also rejected the new system and threatened to kill any Palestinians who cooperate with the Israeli military. The killings early Wednesday were carried out by the Hamas-run police’s Sahm unit, which Hamas says it established to combat looting.

The unit released video footage showing several dead men lying in the street, saying they were Abu Shabab fighters who had been detained and killed for collaborating with Israel. It was not possible to verify the images or the claims around them.

Mohammed Abu Amin, a Khan Younis resident, said he was at the scene of the killings and that crowds were celebrating them, shouting “God is greatest” and condemning those killed as traitors to the Palestinian cause and agents of Israel.

Ghassan Duhine, who identifies himself as a major in the Palestinian Authority’s security forces and deputy commander of the Abu Shabab group, posted a statement online saying they clashed with Sahm and killed five. He denied that the images shared by Sahm were of Abu Shabab fighters.

The Palestinian Authority, led by rivals of Hamas and based in the Israeli-occupied West Bank, has denied any connection to the Abu Shabab group, but many of the militiamen identify themselves as PA officers.

Mounting lawlessness as Israel steps up military campaign

Israel renewed its offensive in March after ending a ceasefire with Hamas and imposed a complete ban on imports of food, fuel, medicine and other aid before easing the blockade in mid-May.

The ongoing war and mounting desperation have plunged Gaza into chaos, with armed gangs looting aid convoys and selling the stolen food. The Hamas-run police force, which maintained a high degree of public security before the war, has largely gone underground as Israel has repeatedly targeted its forces with airstrikes. The military now controls more than half of the territory.

The war began when Hamas-led militants attacked southern Israel on Oct. 7, 2023, killing some 1,200 people, mostly civilians, and taking 251 hostage. They are still holding 53 captives, less than half of them believed to be alive, after most of the rest were released in ceasefire agreements or other deals.

Israel’s military campaign has killed over 55,000 Palestinians, according to the Gaza Health Ministry, which has said women and children make up more than half of the dead. It does not say how many of those killed were civilians or combatants.

Israel’s offensive has flattened large areas of Gaza and driven around 90% of the population of roughly 2 million Palestinians from their homes. The territory is almost completely reliant on humanitarian aid because nearly all of its food production capabilities have been destroyed.
