The U.S. State Department has issued a warning to American citizens visiting Europe this summer to be on the alert for terrorism risks. Targets could include major sporting events and tourist sites, restaurants, commercial centers and transportation, says the State Department.

According to Al Jazeera, while France is under an extended state of emergency following last year’s deadly terrorism attacks in Paris, it will still be the site of the Euro 2016 football championship from June 10 to July 10, as well as the annual Tour de France.

The State Department warning expires August 31.
