“While local governments continue counterterrorism operations, the Department remains concerned about the potential for future terrorist attacks,” the State Department said. “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.”

Terrorists continue to focus on tourist locations, transportation hubs, markets and shopping malls, and local government facilities as targets. Also vulnerable are hotels, clubs, restaurants, places of worship, parks, high-profile events, educational institutions, and airports, the State Department reported.
