Finland began building a 10-foot-tall, 125-mile-long chain link fence on part of its border with Russia on Tuesday over fears Moscow would use migrants for political pressure.

The works of the pilot section, three kilometers long and close to the town of Imatra, began on Tuesday “by clearing forests, and will continue to allow the construction of a road and the installation of a metal fence,” the border guard said in a statement . .

Between 2023 and 2025, the construction of another 70 kilometers is planned, mainly in the southeast. In total, Finland plans to build one of 200 kilometers by 2026, at a cost of 380 million euros ($402 million).

The fence will have barbed wire, night vision cameras, lights and loudspeakers in areas considered sensitive.

Currently, Finland’s 1,300 km long border with Russia is mainly protected by small wooden fences, mainly designed to prevent the movement of livestock.

Estonia, Latvia and Poland have also increased or plan to increase security on their borders with Russia.
