The Israel Defense Forces announced the incursion just over a day after breaking the ceasefire with a sprawling bombing campaign that killed hundreds across the enclave.

Israel is making plans for a potential major ground offensive in Gaza that would involve sending tens of thousands of troops into combat to clear and occupy large swaths of the enclave, an Israeli official and a second source familiar with the matter said.

Israel will take more territory in Gaza and fight until Hamas is wiped out if the Palestinian militant group keeps refusing to free remaining hostages, Israeli Defence Minister Israel Katz said on Tuesday.
