Several cruise lines have rescheduled upcoming calls at Tunis, Tunisia, due to recent anti-American unrest in the region. The U.S. State Department on Sept. 15 issued a warning against travel to Tunisia and ordered the departure of all non-emergency U.S. government personnel after the attack on the U.S. Embassy in Tunis.

Silversea Cruises said the Silver Cloud’s Sept. 30 call to Tunis, Tunisia, would be replaced by Gozo Island, a small island that’s part of the Maltese archipelago in the Mediterranean Sea.

Azamara Club Cruises said the Azamara Quest’s scheduled stop in La Goulette (Carthage), Tunisia, on Oct. 31 will be replaced with a full-day visit to Minorca in the Balearic Islands on Nov. 1.

Holland America Line, which replaced a Tunisia call on Sept. 18 with Cagliari, Sardinia, said the Ryndam on Sept. 28 will instead call in Naples, Italy, while the Noordam’s Oct. 2 call will be made in Cagliari, Sardinia, instead of Tunisia. Noordam also is scheduled to visit Tunisia on Oct. 20, but the line said a decision on whether to proceed will be made as the date gets closer.

Holland America’s Prinsendam is scheduled to call in Egypt at Alexandria on Oct. 3 and Port Said on Oct. 4. “We will continue to monitor the situation and if any adjustments are required, the decision will be made closer to the call date,” the company said.
