Israel resumes mass strikes on Gaza, ending January ceasefire

Israel launched a surprise wave of airstrikes across Gaza after nearly two months of ceasefire. Reuters reported more than 400 Palestinians killed, with hospitals overwhelmed and Israeli officials warning more attacks would follow. Netanyahu said the strikes followed Hamas rejecting ceasefire-extension proposals; Hamas accused Israel of destroying permanent-ceasefire negotiations and endangering hostages. This is the canonical event for the collapse of the January 2025 ceasefire and should remain separate from the January deal and first hostage-prisoner exchange.
