iStock/Thinkstock(WASHINGTON) — The U.S. has extended an alert for summer travel to Europe amid concerns that major public events could be targets for terror attacks.

A continent-wide alert for Europe that was put in place in March and set to expire in June has been extended through the end of August. According to the State Department, “The large number of tourists visiting Europe in the summer months will present greater targets for terrorists planning attacks in public locations, especially at large events.”

The State Department highlighted the Euro 2016 football championship that will be held in France starting next month, where there is already a state of emergency after the deadly Paris attacks in 2015.

The alert also mentions the Catholic Church’s World Youth Day set to take place in July in Krakow, Poland.

According to White House Press Secretary Josh Earnest, there is no specific terror threat in Europe. The alert serves as a reminder to “stay vigilant” during summer travel.

“I’m not aware of any specific, credible, terrorist threat around these events or in any particular place in Europe,” Earnest said Tuesday. “This alert was issued just as they always are based on an accumulation of information and what we know continues to be an interest by terrorists groups to conduct attacks against western targets and Americans specifically in Europe.”
