For the third time in just a few months, the undersea data cable C-Lion1, connecting Finland and Germany, has been damaged.

The latest incident occurred near Sweden's Gotland Island, within its exclusive economic zone.

Swedish authorities have launched an investigation into possible sabotage, though the exact cause remains unclear.

The cable, vital for telecommunications between Northern and Central Europe, continues to function despite the damage.

This follows a series of similar incidents in the Baltic Sea, raising concerns about the security of critical infrastructure.

NATO has increased its presence in the region under the "Baltic Sentry" mission to protect undersea assets.

The European Union is also stepping up efforts to monitor and repair such infrastructure swiftly.

Experts suspect that ships dragging anchors may be responsible, either accidentally or intentionally.
