French President Emmanuel Macron said on Wednesday the quartet London meeting with Turkish, British and German leaders was “very useful.”

“I’m very happy that we had a very useful meeting yesterday with British Prime Minister, Chancellor Merkel and President Erdogan, Macron told a press conference after the NATO leaders’ summit in London.

The meeting, which helped clarify various issues, also “allowed us … to reaffirm our priority in fighting IS [Daesh/ISIS], and our common commitment to the refugee issue and a political solution to the Syrian conflict,” the French leader said, in remarks translated into English.
