U.S. Issues Alert to Americans Traveling in Europe

The Search for Al Qaeda: Its Leadership, Ideology, and Future, Revised edition
On October 3rd, the U.S. State Department issued a Travel Alert to Americans traveling in Europe, warning them to be alert as al-Qaeda and affiliated terrorist groups "continue to plan terrorist attacks."
While the State Department does not say it has specific information about an impending attack, it does cite the potential for terrorists to attack tourist infrastructure and transportation systems including "subway and rail systems, as well as aviation and maritime services."
It is worth noting that in the past the State Department has rarely if ever issued a Travel Alert, or a more long term and serious Travel Warning, on a Sunday.
