“It will happen. There is a date,” Netanyahu said in a video statement Monday, without elaborating.

The United States, Israel’s closest ally, has said a ground operation into Rafah would be a mistake and has demanded to see a credible plan to protect civilians. Netanyahu spoke as Israeli negotiators are in Cairo discussing international efforts to broker a cease-fire deal with the Palestinian militant group Hamas.

Israeli troops withdrew Sunday from Khan Younis, another city in southern Gaza, ending a key phase of the war. Defense officials say they’re regrouping ahead of a push into Rafah. Palestinians who visited Khan Younis on Monday said the city is now unlivable, offering them little immediate chance to return. Many have been sheltering in Rafah.

The Palestinian death toll from the war has passed 33,200, with nearly 76,000 wounded, Gaza’s Health Ministry said. The ministry doesn’t differentiate between civilians and combatants in its tally, but says women and children make up two-thirds of the dead.
