The Norwegian coast guard detained a ship on Friday whose crew is suspected of involvement in damaging underwater cables in the Baltic Sea. The vessel, flying the Norwegian flag, was detained in the port of Tromsø.

The Silver Dania was brought into the port of Tromsø in northern Norway after damage to a cable connecting Latvia and the Swedish island of Gotland.

Norwegian authorities on Friday said they seized a commercial ship with an all-Russian crew suspected of damaging an undersea telecom cable in the Baltic Sea.

Sweden has opened a preliminary investigation into suspected aggravated “sabotage” and ordered the detention of a vessel in the Baltic Sea suspected of damaging an underwater fiber optic cable connecting Latvia and the Swedish island of Gotland

Swedish authorities have seized a ship over the “aggravated sabotage” of an undersea fibre-optic cable linking Latvia with a strategically important island in Sweden.

Earlier this month, NATO began a new mission dubbed "Baltic Sentry" which included frigates, maritime patrol aircraft and a fleet of naval drones to provide "enhanced surveillance and deterrence" in the Baltic Sea which the transatlantic alliance says is to protect undersea cables and pipelines.

The authorities said they believed the vessel may have been involved in damaging the cable, the latest act of apparent sabotage in the Baltic Sea.
