WASHINGTON: The US State Department issued a travel alert for Europe on Monday, saying US citizens should be aware of a continued threat of terrorist attacks throughout the continent. In the alert, the State Department cited recent incidents in France, Russia, Sweden and the United Kingdom and said Daesh and al-Qaeda “have the ability to plan and execute terrorist attacks in Europe.” The State Department’s previous travel alert for Europe, issued ahead of the winter holiday season, expired in February. A State Department official said Monday’s alert was not prompted by a specific threat, but rather recognition of the continuing risk of attacks especially ahead of the summer holidays. The alert expires on Sept. 1. Malls, government facilities, hotels, clubs, restaurants, places of worship, parks, airports and other locations are all possible targets for attacks, the State Department’s alert said.
