Israeli Prime Minister Benjamin Netanyahu spurned a plea from Joe Biden to call off a planned ground assault of Rafah, the last refuge in Gaza for more than a million displaced people, where Israel believes Hamas militants are holed up, Reuters reports.

Netanyahu told lawmakers on Tuesday he had made it “supremely clear” to the US president “that we are determined to complete the elimination of these battalions in Rafah, and there’s no way to do that except by going in on the ground”.

The two leaders spoke by phone on Monday. White House National Security Adviser Jake Sullivan said Washington believed that storming Rafah would be a “mistake” and that Israel could achieve its military aims by other means.

US and Israeli officials will likely meet early next week in Washington to discuss Israel’s military operation in Rafah, White House spokesperson Karine Jean-Pierre said on Tuesday, citing deep concern about reports of imminent famine in Gaza.

Jean-Pierre said Biden had asked Netanyahu to send a senior team of military, intelligence and humanitarian officials to Washington for comprehensive discussions in the coming days.

Washington has launched a new diplomatic push for a ceasefire in the nearly six-month-old conflict to free hostages and bring in food aid to ward off famine in the Palestinian enclave.
