Prime Minister Benjamin Netanyahu’s office said he had ordered the aerial attacks after Hamas’s “repeated refusal” to release the remaining hostages it holds. “This is just the beginning,” he said.

Israel said the Tuesday attacks were launched after Hamas refused to release more hostages held in Gaza. The strikes raise the prospect of a full resumption of war after a nearly two-month ceasefire.

Israel Air Force jets reportedly struck Tuffah, east of Gaza City, on Tuesday night.
