Israel will continue its offensive on Rafah, while guaranteeing the evacuation of civilians, Prime Minister Benjamin Netanyahu said.
Egypt is building a concrete wall along its border with Gaza to protect itself from potential refugees fleeing Israel's military operation against Hamas in Gaza.
Biden discussed with Netanyahu the need to develop a realistic plan to ensure the safety of civilians during any operation in Rafah and to provide more emergency aid to Gaza.
Biden calls for a six-week ceasefire between Israel and Hamas to allow time for negotiations on a long-term peace agreement.
Israeli air strikes and shelling of the Palestinian city of Rafah reportedly killed more than 100 people.
Israeli strikes on the Rafah refugee camp in Gaza reportedly killed 37 people and injured dozens.
Israeli Prime Minister Netanyahu said that the IDF will conduct a large-scale operation in the city of Rafah in Gaza to disband Hamas battalions, and more than 1. 3 million Palestinian refugees living there will be evacuated first.
According to an Israeli intelligence officer, the elimination of the Hamas threat will take all of 2024 or longer.
