Norwegian police seized a Russian-crewed ship on suspicion of being involved in causing “serious damage” to a fiber cable in the Baltic Sea between Latvia and Sweden.

The authorities said they believed the vessel may have been involved in damaging the cable, the latest act of apparent sabotage in the Baltic Sea.

Swedish authorities have seized a ship suspected of damaging a data cable running under the Baltic Sea to Latvia. The Vezhen - a Maltese-flagged ship - is now anchored outside the Swedish port of Karlskrona.

Authorities in northern Norway released a vessel that was suspected of the latest data cable breach in the Baltic Sea, saying no evidence had been found linking it to the incident.
