Weather conditions and deficiencies in equipment and seamanship” were behind last month’s disruption, prosecutors say.

The cargo ship Vezhen did damage a subsea cable linking Sweden and Latvia last month but it was an accident, not sabotage, a Swedish prosecutor said on Monday, adding that the Maltese-flagged vessel had been released.

Russia’s state-controlled telecom giant Rostelecom announced on Feb. 8 that one of its underwater cables in the Baltic Sea had been damaged due to an "external impact." The company did not specify the cause of the damage but confirmed that repair work was underway.
