"An underwater data cable between Sweden and Latvia was damaged early on Sunday," reports the Financial Times, "in at least the fourth episode of potential sabotage in the Baltic Sea that has caused concern in Nato about the vulnerability of critical infrastructure..."

Criminal investigations have started in Latvia and Sweden, and a ship has been seized as part of the probes, according to Swedish prosecutors, who did not identify the vessel. Previous incidents have been linked to Russian and Chinese ships...

The latest incident comes as the three Baltic states are preparing to disconnect their electricity systems from the former Soviet network in early February and integrate themselves into the continental European grid, with some fearing further potential disruption ahead of that. Estonia, Latvia and Lithuania have joined the EU and Nato since regaining their independence after their forced annexation by the Soviet Union, and see their switch to the European electricity system as their final integration into the west. KÄ(TM)stutis Budrys, Lithuania's foreign minister, said navigation rules in the Baltic Sea needed to be reviewed "especially when it comes to the use of anchors" and added there were now so many incidents that there was little chance they could all be accidents.

Repair of data cables has tended to take much less time than that for gas or electricity connections, and the Latvian state radio and television centre said it had found alternative routes for its communications.
