The rupture is being examined in the context of ongoing investigations into underwater infrastructure damages, including a recent breakage of the Balticconnector pipeline between Estonia and Finland. Officials have not confirmed sabotage but treat it as one viable hypothesis. The cable cut disrupted communication between Estonia and Sweden, occurring shortly after another undersea cable between Estonia and Finland was damaged. Prosecution evidence suggests the damage was man-made, and the breakages are being collectively investigated.
