Norway's Hurtigruten is calling off cruising operations until 2021.
The company said it has decided to cancel all Expedition cruises after an increase in Covid-19 cases across Europe and South and North America.
"Hurtigruten is closely monitoring the developments regarding Covid-19," the cruiseship and ferry operator said on Thursday.
"We are proactive when it comes to the health and safety of our guests, crew and staff as this is Hurtigruten's number one priority."
