Speaking alongside Israeli Prime Minister Benjamin Netanyahu in Jerusalem, Macron stressed that France and Israel share terrorism as their "common enemy", but gave little detail on how the US-led coalition of dozens of countries could be involved.

"France is ready for the international coalition against Daesh in which we are taking part for operations in Iraq and Syria to also fight against Hamas," he told reporters, referring to Islamic State and promising not to leave Israel alone.

Macron also warned against the risks of a regional conflict, stressing the fight against Hamas "must be without mercy but not without rules".
