Cruise lines that are calling at the French Riviera canceled shore excursions and port calls to Nice, following the terrorist attack on July 14.

A number of lines including P&O Cruises, MSC Cruises, Royal Caribbean, Norwegian Cruise Line, Regent Seven Seas and Oceania Cruises have either port calls to Nice/Villefranche or shore trips from nearby ports, such as Cannes and Monaco, scheduled in the next few days.

A truck driver accelerated into crowds of revelers celebrating the Bastille Day, killing 84 people.

Neither the U.K. FCO (Foreign & Commonwealth Office) nor the U.S. State Department altered their travel advice to France.

FCO issued the following statement:

"If you're in the area, follow the instructions of the French authorities, who have canceled a number of public events planned for the coming days, closed the Promenade des Anglais and a number of the public beaches in and around Nice, and implemented some traffic restrictions."



Here is where cruise lines stand:

P&O Cruises' flagship mv Britannia was in Cannes yesterday. A spokeswoman for the company confirmed:

"All shore excursions to Nice have been canceled and passengers have been advised to avoid Nice centre."

Royal Caribbean: Navigator of the Seas was due to call at Nice yesterday, and sister line's Celebrity Constellation today. A statement read:

"After reviewing all of the available information and along with discussions with our Global Security team in Miami, we have decided to cancel our next two calls to Nice. Navigator of the Seas was scheduled to visit Nice on Friday, July 15. Instead, the ship will spend the day at sea. Celebrity Constellation was due to visit Nice on Saturday, July 16. Instead, the ship will sail to Livorno, the next scheduled port of call, where it will now arrive earlier on Saturday and stay overnight."

The company confirmed that it would "continue to monitor the situation" should there be any need to make further changes.

MSC Cruises said in a statement, it was "providing [passengers] with an option to either cancel for full refund or change shore excursion plans," but added "there is currently no restriction in place by the local security forces that would make this mandatory."
