Israeli strikes killed at least 58 Palestinians across the Gaza Strip overnight and into Thursday, according to three hospitals. The strikes hit multiple homes in the middle of the night, killing men, women and children as they slept.

Israel resumed heavy strikes across Gaza on Tuesday, shattering a ceasefire that had halted the war and facilitated the release of more than two dozen hostages. Israel blamed the renewed fighting on Hamas because the militant group rejected a new proposal that departed from their signed agreement.

More than 400 Palestinians were killed on Tuesday alone, mostly women and children, according to Gaza’s Health Ministry. There have been no reports of Hamas firing rockets or carrying out other attacks.

One of the strikes early Thursday hit the Abu Daqa family’s home in Abasan al-Kabira, a village just outside of Khan Younis near the border with Israel. It was inside an area the Israeli military ordered evacuated earlier this week, encompassing most of eastern Gaza.

The strike killed at least 16 people, mostly women and children, according to the nearby European Hospital, which received the dead. Those killed included a father and his seven children, as well as the parents and brother of a month-old baby who survived along with her grandparents.

“Another tough night,” said Hani Awad, who was helping rescuers search for more survivors in the rubble. “The house collapsed over the people’s heads.”

Israeli ground troops advance

On Wednesday, Israeli ground troops advanced in Gaza for the first time since the ceasefire took hold in January, seizing part of a corridor separating the northern third of the territory from the south.

Israel, which has also cut off the supply of food, fuel and humanitarian aid to Gaza’s roughly 2 million Palestinians, has vowed to intensify its operations until Hamas releases the 59 hostages it holds — 35 of whom are believed dead — and gives up control of the territory. The Trump administration, which took credit for brokering the ceasefire, says it fully supports Israel.
