On Thursday, Israel initiated a fresh series of airstrikes targeting Hamas, reportedly resulting in 27 fatalities. The Israeli Defense Forces (IDF) accused Hamas of consistently testing the military border zone, actions that mediators caution could jeopardize the delicate cease-fire in Gaza.

Reported skirmishes erupted between Hamas militants and Israeli troops in Khan Younis, near the “Yellow Line”—the border to which the IDF had retreated in Gaza. This clash prompted Israel to launch another wave of air raids on the Strip.

The strikes claimed at least 27 lives and left 88 individuals wounded, elevating the Palestinian death toll to 307 since the cease-fire was established last month. These figures, provided by the Hamas-run local health ministry, do not distinguish between combatants and civilians.

Qatari mediators, instrumental in brokering the cease-fire, express grave concern over the ongoing hostilities and lethal airstrikes in Gaza, warning that these incidents could unravel the fragile peace efforts.

Qatar’s foreign ministry condemned the “brutal attacks by the Israeli occupation in the Gaza Strip,” labeling them as a significant escalation that could destabilize the cease-fire agreement.

Doha also called for the international community to unite to preserve the cease-fire and ensure that all-out war does not erupt inside Gaza.

The IDF, which still controls about 53% of Gaza, has accused Hamas of repeatedly violating the terms of President Trump’s cease-fire deal by going past the Yellow Line, a border demarcated by literal yellow blocks and paint that splits the Palestinian enclave in half.

Since the cease-fire went into effect on Oct. 10, Hamas has allegedly trespassed the military border daily and engaged in multiple fights with IDF troops, allegations the terror group has denied.

There have been at least three major conflicts along the Yellow Line since the cease-fire began, including one that saw two IDF soldiers killed, with Israel retaliating with airstrikes every time.

Lt. Col. Nadav Shoshani, who operates at a base near the Yellow Line inside Gaza City, said there have been hundreds of Hamas violations during the cease-fire.

“Hamas tests us daily,” he told the Times of Israel during a tour of the border on Wednesday.

Shoshani also warned that the alleged attacks from Hamas was proof that the terror group would not cede its weapons as demanded in the US-backed peace deal.

The renewed tensions come just two days after the UN Security Council voted to approve the introduction of an international board to govern and police the Gaza Strip, as laid out in Trump’s 20-point peace plan.

Despite the approval, there remains lingering questions over which nations would commit to sending its forces to deal with Hamas, which has repeatedly stated that it would not disarm until a pathway is established for a Palestinian state.
