Italian liner Costa Classica, carrying 1000 passengers on a Mediterranean cruise, has cancelled scheduled stops in Turkish ports for security reasons following the bombings.

Pier Luigi Foschi, the head of Costa Crociere, which owns the vessel, said: "Even before Italian authorities warned against non-essential trips to Turkey, we decided to re-route our ship, as a precaution, to Cyprus and Rhodes." 

The stops of Izmir and Antalya had been scheduled for Friday and Saturday.

Whether or not future winter cruises will also be re-routed, will be decided at a later date case by case, Foschi added at the launching in Genoa of the Costa Fortuna, the biggest passenger liner ever built in Italy.

A number of Western countries have advised travelers to avoid Turkey after at least 53 people died and hundreds were wounded in bomb attacks against two synagogues and British interests in Turkey's metropolis.
