Unofficially yes. But to be exposed in public like this IMHO it is an international incident, a diplomatic disaster for the United States government and the president too.
This is an incident because nations never formally admit that they listen to others.
I would have an international manhunt underway for Snowden. He would not be safe anywhere in the world....but then, that why I am not the leader and Obama is. If only he knew how to handle things like this....but alas his incompetence shows every day.
