Israel and Egypt are negotiating the future of a corridor between Egypt and Gaza that Israel says has been used by Hamas to smuggle weapons and people through underground tunnels and is key to destroying the militant group.

Israel has requested that sensors be installed along the Philadelphi Corridor—the sliver of land controlled by Egypt that borders Gaza—according to senior Egyptian officials, to alert Israel in case Hamas attempts to rebuild a tunnel and smuggling network after the war. Israel, which used to control the corridor, also requested direct notifications if the sensors are triggered and the right to send surveillance drones into the area in case of such a trigger, the officials said.
