Investigators are looking into the death of a foreign cruise ship passenger, who lost his life during an excursion to the northern port city of Murmansk, the Interfax news agency reported Wednesday.
The foreign citizen, who was not identified in the report, died Tuesday after falling unwell during a trip to one of the city's monuments, Interfax cited a source within the regional branch of the Investigative Committee as saying.
Unconfirmed reports stated the man was a U.S. citizen, Interfax added.
Murmansk, located on the Barents Sea, is used as a port call for several companies offering cruises in Arctic waters.
