DEIR AL-BALAH, Gaza Strip: Israel said Tuesday that its troops had entered Gaza’s second-largest city as intensified bombardment sent streams of ambulances and cars racing to hospitals with wounded and dead Palestinians, including children, in a bloody new phase of the war. The military said its forces were “in the heart” of Khan Younis, which has emerged as the first target in the expanded ground offensive into southern Gaza that Israel says aims to destroy Hamas. Military officials said they were engaged in the “most intense day” of battles since the ground offensive began more than five weeks ago, with heavy firefights also taking place in northern Gaza. The assault into the south is pushing a new wave of displaced Palestinians almost two months into the war, raising alarm from relief groups that they can’t keep up because insufficient aid supplies are entering Gaza. The UN said 1.87 million people — more than 80 percent of Gaza’s population — have been driven from their homes. New evacuation orders by the Israeli military are squeezing people into ever-smaller areas of the tiny coastal strip’s southern portion.Bombardment has grown fiercer across the territory, including areas where Palestinians are told to seek safety. In the central Gaza town of Deir Al-Balah, just north of Khan Younis, a strike Tuesday destroyed a house where dozens of displaced people were sheltering. At least 34 people were killed, including at least six children, according to an Associated Press reporter at the hospital who counted the bodies. Footage from the scene of the strike showed women screaming from an upper floor of a house shattered to a concrete shell. In a field of wreckage below, men pulled the limp body of a child from under a concrete slab next to a burning car. At the nearby hospital, medics tried to resuscitate a young boy and girl, placed together bloodied and unmoving on a single stretcher. Under US pressure to prevent further mass casualties in the conflict with Hamas, Israel says it is being more precise as it widens its offensive into southern Gaza. Weeks of bombardment and a ground offensive obliterated much of northern Gaza. Israel’s assault since Oct. 7 has killed more than 15,890 people in Gaza — 70 percent of them women and children — with more than 42,000 wounded, according to the Health Ministry in Gaza. The ministry does not differentiate between civilian and combatant deaths. It says hundreds have been killed or wounded since a weeklong ceasefire ended Friday, and many still are trapped under rubble.
