An undersea fiber optic cable between Latvia and Sweden was damaged on Sunday, likely as a result of external influence, Latvia said, triggering an investigation by local and NATO maritime forces in the Baltic Sea.

Latvia on Sunday said it had sent a warship to investigate the latest apparent act of sabotage in the Baltic, as Sweden reported at least one undersea optic fibre cable linking the two countries had been damaged.

There have been a string of incidents in which power cables, telecom links and gas pipelines have been damaged in the wake of Russia's invasion of Ukraine in February 2022.
