US unpredictability impacts our interests, France army chief says

France's army chief said on Tuesday that the United States had become an unpredictable ally that was impacting France's interests and security.

"We were surprised by an American ally, who remains an ally, but who is becoming increasingly unpredictable and doesn't even bother to inform us when they decide to launch military operations," Fabien Mandon told a security and defence forum in Paris.

"It has an impact on our security and it has an impact on our interests."
