All U.S. military personnel are banned from traveling to or within France in the wake of a string of terrorist attacks that left 129 dead, including one American.

U.S. European Command announced on Sunday the travel restrictions on unofficial trips to and within France.

"This EUCOM policy applies to United States military personnel, DoD civilian employees, contractors and command-sponsored dependents and family members," according to a European Command statement.

Any requests for official travel or emergency leave to France must be approved by the first general officer or senior executive service civilian in that person's chain of command.

The restrictions also apply to tourist cruise ship-to-shore excursions, but do not apply to layovers on connecting flights as long as personnel do not leave the airport.

"This is a precautionary measure to keep our personnel and families safe in light of the recent attacks. This is also an effort to help minimize tourist traffic at the borders in France, and in particularl, in Paris as the French authorities continue their investigation," European Command said.

A string of six attacks at restaurants, sports stadiums and concert halls across Paris on Friday afteroon killed 129 people and injured more than 350. The French announced over the weekend that the Islamic State was behind the terrorist attack. The group took credit in a message posted online, promising more violence for those who are taking part in airstrikes against the group in the Middle East.

In response to the attacks, France has increased its participation in the coalition striking the Islamic State, hitting the declared caliphate in Raqqah, Syria, on Sunday.

The Islamic State threatened an attack on D.C. and other countries participating in airstrikes in Syria, Reuters reported on Monday.
