Hello and welcome back to the Guardian’s live coverage of the war in Gaza and the wider crisis in the Middle East.

Israeli strikes have killed at least 58 Palestinians across the Gaza Strip overnight, according to three hospitals.

The Associated Press reports 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.

These latest strikes come a day after 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.

We’ll bring you the latest developments throughout the day.
