Nato secretary-general Mark Rutte said on Friday that the military alliance will step up patrols in the Baltic Sea region as Finnish investigators work to establish whether a ship linked to Russia sabotaged undersea cables there this week.

Finnish authorities seized control of the ship, the Eagle S, on Thursday as they tried to establish whether it had damaged a power cable linking Finland and Estonia and several data cables.
