The Latest | Netanyahu vows to carry out Rafah invasion, which US says would be a mistake

Israeli Prime Minister Benjamin Netanyahu has escalated his pledge to invade the southern Gaza city of Rafah, which is filled with around 1.4 million Palestinians, most of whom are displaced from other parts of the Gaza Strip.

“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.
