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 connect

Sweden on Sunday said it had seized a ship suspected of having damaged a fibre-optic cable under the Baltic Sea linking the country to Latvia, which sent a warship to investigate the latest apparent act of sabotage.

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.
