France has restored border controls through June 4 as a security precaution for the G8 summit in Evian, near Geneva. Authorities say controls are also in place on French highways and in train stations, including in Paris.

A strike by air traffic controllers in France in support of striking teachers wreaked havoc on air travel throughout France May 27, and more may be coming. Union leaders have vowed to stage open-ended strikes beginning June 3 if demands to limit pension reforms are not met. The government may be hoping to hold out until June 28, when school summer holidays begin, and the teachers’ strikes could lose their momentum. If so, travel in France may be disrupted throughout much of June.
