US State Department warns travelers of terror attacks on European targets

The U.S. State Department warned Americans on Tuesday of the possible threat of terrorist attacks in Europe this summer, saying targets could include tourist sites, restaurants, commercial centers and transportation.

"We are alerting U.S. citizens to the risk of potential terrorist attacks throughout Europe, targeting major events, tourist sites, restaurants, commercial centers and transportation," it said in a travel alert expiring Aug 31.

"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."
