Finland sends border guards to Latvia's Belarus frontier

Summary

A look back at the Finnish decision of 5 September 2025 and the espionage arrests in Belarus a day earlier.

What did Finland agree to on 5 September 2025? It accepted a request from Latvia to deploy border guards on the Belarus–Latvia border, to help manage increased migration from Belarus. Estonia and Lithuania were also providing support.

The decision was reported under the heading of the Belarus–European Union border crisis, and it linked Finland and Latvia directly through border security.

Arrests in Belarus

The previous day, 4 September 2025, Belarus detained a Polish national and a Belarusian citizen on espionage charges. Authorities alleged that the two had possessed documents on Zapad 2025. The reports concerned Belarus–Poland relations.

The two developments came on consecutive days. Both involved Belarus and its neighbours' security concerns, though the reports did not link them to each other.
