A Norwegian-owned, Russian-crewed ship that authorities initially suspected of involvement in damage to an underwater fiber optic cable connecting Latvia and the Swedish island of Gotland has been released.

Norway has detained the Silver Dania on suspicion of involvement in damaging a fiber optic cable in the Baltic Sea. The ship's crew are Russians, Dagbladet reports. Norwegian police said they had seized the Silver Dania based on a legal request from Latvia and a court order.

After a series of suspected undersea cable cuttings, NATO has launched a new surveillance and deterrence mission to protect critical infrastructure under the Baltic Sea.
