Swedish and Finnish police are investigating a suspected case of sabotage of an undersea telecoms cable in the Baltic Sea, and Sweden's coast guard has deployed a vessel to the area where multiple seabed cables have been damaged in recent months.

Swedish and Finnish police are investigating a suspected case of sabotage to the telecom system in the Baltic Sea, after multiple seabed cables were damaged in recent months. Finnish operator Cinia on Friday said it had detected problems on its C-Lion1 fibre-optic link connecting Finland and Germany some time ago and that it was confirmed this week that the cable was damaged even as data traffic continued to flow.

Swedish authorities said Friday they were investigating a damaged cable that was discovered in the Baltic Sea , the latest in a string of recent incidents of ruptured undersea cables that have heightened fears of Russian sabotage and spying in the region.
