In a troubling development that highlights ongoing security issues in the Baltic Sea, an undersea power cable connecting Finland and Estonia suffered a breakdown on Wednesday.

This incident is part of a series of disruptions affecting cables and energy pipelines in the region.

Finnish Prime Minister announced the incident, while Arto Pahkin, head of operations for Finland’s electricity grid, did not dismiss the possibility of sabotage.

Tensions are mounting, given the strategic importance of these infrastructures for regional energy security and the series of similar incidents recently reported.
