A summit involving the leaders of Egypt, Israel and U.S. President Donald Trump is being considered following this week’s major gas deal between Cairo and Tel Aviv, a source familiar with the plans said Thursday.

An Egyptian team is preparing a visit by President Abdel-Fattah el-Sissi to the U.S., the source told dpa.

This could form the basis of a three-way summit with Trump and Israeli Prime Minister Benjamin Netanyahu, they added. There has been no official confirmation.

A meeting between the two would be an unexpected development and previously unthinkable due to the war in the Gaza Strip, which borders both countries.

Egypt and Israel are deeply divided on a range of issues relating to Gaza, including the operation of the Egyptian border crossing at Rafah, the situation in the shared border area and the status of the Palestinians.
