Fears are mounting the war could be widening, with Iran and its proxies stepping up attacks across the region Massive explosions could be seen over northern areas of Gaza from across the border with Israel GAZA: Israeli tanks stormed back into parts of the northern Gaza Strip they had left last week, residents said on Tuesday, reigniting some of the most intense fighting since the New Year when Israel announced it was scaling back its operations there. Massive explosions could be seen over northern areas of Gaza from across the border with Israel — a rarity over the past two weeks after Israel announced a draw-down of forces in the north as part of a transition to smaller, targeted operations. The rattle of intense gunfire carried across the border through the night. In the morning, contrails snaked through the sky as Israel’s Iron Dome defenses shot down rockets fired by militants across the fence, proof they retain the capability to launch them despite more than 100 days of war. Israel said its forces had killed dozens of Hamas fighters overnight in clashes in Beit Lahiya on the northern edge of the Gaza Strip. Gaza health authorities said the last 24 hours of Israeli bombing had killed 158 people in the enclave, raising their toll for the war, now in its fourth month, to 24,285, with thousands more bodies feared lost in the rubble. Israel launched the war to eradicate Hamas after militants stormed across the border fence on Oct. 7, killing 1,200 people and capturing 240 hostages. The war has driven nearly all Gazans from their homes, some several times, and caused a humanitarian crisis, with food, fuel and medical supplies running low. Under pressure from Washington to reduce civilian casualties, Israel had said it was shifting tactics, transitioning from a full-scale ground assault to targeted operations against the Hamas militants that control the enclave. It began that shift with a pullback in the north, where its forces had begun their ground offensive in October. On Monday evening, Defense Minister Yoav Gallant also said the more recent ground assault in the south was drawing to a close. But any path toward de-escalating the war still seems remote, with Israel saying it will not halt until Hamas is destroyed, and the fighters showing no sign of losing the ability to resist. Some of the hundreds of thousands of residents who fled the north earlier in the war had begun returning last week to bombed-out areas where the Israelis had withdrawn. But residents who spoke to Reuters on Tuesday said the abrupt resurgence of fighting in the north would now halt plans to try to go home. “We almost planned to return to our house in Nazla, east of Jabalia, but thank God we didn’t. This morning people living nearby arrived here and told us the tanks pushed back there,” said Abu Khaled, 43, a father of three now living with relatives in severely damaged Gaza City. “The sounds of bombing from the tanks, from the planes didn’t stop all night. It reminded us of the first day of the ground incursion,” he said. Israeli forces have fought their way to the center of Gaza’s main southern city of Khan Younis, and into towns north and east of the central city of Deir Al-Balah. Defense Minister Gallant’s announcement on Monday that the major ground offensive in the south would soon come to an end raises the question of whether the Israelis will still try to advance into the remaining southern areas. Most of Gaza’s 2.3 million people are now crowded into the few southern areas that Israeli troops have yet to enter, including Deir Al-Balah and Rafah, which is located on the southern edge of the strip. In Khan Younis, Zaher Abu Zarifa wept and cradled a black plastic body bag holding his seven-year-old son Saif, one of at least 11 bodies brought out at a hospital morgue. The boy was killed by a missile while playing on a bicycle by a school gate, his father said. Later, by a small freshly dug grave, a gravedigger unzipped the bag so the father could kiss the boy’s face, then zipped it back up, took the boy and gently laid him in the ground. “Forgive me, my son. I could not protect you,” the father repeated. “Forgive me, my son. I could not protect you.” Iran strikes Iraqi Kurdish region In the latest example of the conflict spreading to other parts of the Middle East, Iran fired missiles at what it called an Israeli spy base in northern Iraq’s Kurdish region, killing four people in the regional capital Irbil. Masrour Barzani, head of the regional government, called it a “crime against the Kurdish people.” The Iran-aligned Houthi movement that controls most of Yemen has been attacking commercial ships at the mouth of the Red Sea, a route used by 15 percent of world shipping, claiming to target vessels linked to Israel in solidarity with Gaza. The United States and Britain responded by bombing Yemen to prevent what they called a threat to global commerce. The latest ship to be attacked, a Malta-flagged, Greek-owned bulk carrier, sustained minor damage when it was hit with a missile in the Red Sea on Tuesday. Greek sources identified the vessel as MT Zografia. Everyone on board was safe and it was still sailing but would probably reroute for checks.
