Finnish police zero in on four suspects over Baltic subsea cable damage

"The investigation concluded with four suspects, three of whom remain subject to a travel ban," the police said in a statement.

The Baltic Sea region is on high alert after a string of power cable, telecom link and gas pipeline outages since Russia invaded Ukraine in 2022, and NATO has boosted its military presence with frigates, aircraft and naval drones.
