Egypt has rejected an Israeli proposal for the two countries to coordinate to re-open the Rafah crossing between Egypt’s Sinai Peninsula and the Gaza Strip, and to manage its future operation, two Egyptian security sources said, Reuters reports.

Officials from Israeli security service Shin Bet presented the plan on a visit to Cairo, amid rising tension between the two countries following Israel’s military advance last week into Rafah, where hundreds of thousands of Palestinians displaced by conflict have been sheltering.

The Rafah crossing has been a main conduit for humanitarian aid entering Gaza, and an exit point for medical evacuees from the territory, where a humanitarian crisis has deepened and some people are at risk of famine.

Israel took operational control of the crossing and has said it will not compromise on preventing Hamas having any future role there.

The Israeli proposal included a mechanism for how to manage the crossing after an Israeli withdrawal, the security sources said. Egypt insists the crossing should be managed only by Palestinian authorities, they added.
