RIGA: 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.

The latest incident came as nations around the Baltic Sea scrambled to bolster their defences after the suspected sabotage of undersea cables in recent months, with some observers blaming Russia.

Latvia´s navy said it had identified a “suspect vessel”, the Michalis San, which was near the location of the incident along with two other ships. Several websites tracking naval traffic said the Michalis San was headed for Russia.
