The alert said   “While local governments continue counterterrorism operations, the Department nevertheless remains concerned about the potential for future terrorist attacks,”. “U.S. citizens should always be alert to the possibility that terrorist sympathizers or self-radicalized extremists may conduct attacks with little or no warning.”

The alert also made mention of the  recent attacks in France, which elects a new president next week, Sweden and UK, noting that extremists are usually drawn to tourist hot spots.
