The C-Lion1 cable runs alongside the multibillion-dollar Nord Stream 1 and 2 pipelines.
Damage to two undersea fiber-optic communication cables in the Baltic Seaโone between Lithuania and Sweden, and the other between Finland and Germanyโshould be regarded as sabotage, German Defense Minister Boris Pistorius said on Tuesday.
โNo one believes that these cables were cut accidentally. I also donโt want to believe in versions that these were ship anchors that accidentally caused the damage,โ German Defence Minister Boris Pistorius said before meeting of European Union defense ministers.
โSo we have to stateโwithout knowing in concrete terms who it came fromโthat this is a hybrid action. And we also have to assumeโwithout already knowing it, obviouslyโthat this is sabotage.โ
A 218-km (135-mile) internet link between Lithuania and Swedenโs Gotland Island went out of service at about 8 a.m. GMT on Sunday, according to Lithuaniaโs Telia Lietuva, part of Swedenโs Telia Company.
Later, Finnish state-controlled cyber security and telecoms company Cinia revealed that a separate 1,200-kilometre (745-mile) cable connecting Helsinki to the German port of Rostock has also stopped working, around 2 a.m. GMT on Monday,
Teliaโs Chief Technology Officer Andrius ล emeลกkeviฤius told the Lithuanian television station LRT that no cases of sabotage have been recorded so far.
โThese failures are mostly related to shipping, when a ship hooks the cable and breaks it off somewhere in a shallow place, close to the shore, by dropping anchor incorrectly,โ he said on Monday.
Lithuaniaโs Navy said on Tuesday it had subsequently increased the surveillance of its waters.
There are about 400 subsea cables across the world, connecting islands, countries, regions, and continents. Subsea cables, which are about as thick as a garden hose, use optical fiber technology to transmit electronic communications data at the speed of light, according to the European Union Agency for Cybersecurity (ENISA).
The foreign ministers of Finland and Germany said in a Nov. 18 joint statement that they were โdeeply concerned about the severed undersea cable connecting Finland and Germany in the Baltic Sea.โ
