Cruise lines that have scheduled stops at Lesbos have changed their itineraries. The Greek island is where thousands of refugees and migrants have arrived lately.

On Sunday (September 6), Regent Seven Seas altered its itinerary for Seven Seas Mariner. A call at Mytilene was replaced with a day at sea. Riviera, operated by Oceania Cruises, which also had a scheduled stop yesterday at Lesbos, replaced the cruise port call with Kavala, Greece.

Spokesman Jason Lasecki commented on future sailings, that the line would continue to monitor the situation and make itinerary adjustments, if needed.

Silversea also rescheduled a visit to Lesbos for September 26. Instead, Silver Spirit will call at Myrina, Lemnos.

Nearly 20,000 migrants from Africa and the Middle East are currently living in the refugee camps on Lesbos, only six miles from the coast of Turkey. The migrants, many of whom trying to reach Northern Europe, were stuck on the island as the government of Greece tries to register them before continuing their trip, according to Wall Street Journal

Thousands of refugees left one of the camps and marched on Lesbos' capital Mytilene this weekend, burning trash and trees along their way. Clashes with police were reported as well.
