Tensions between Estonia and Russia have escalated through both digital and physical security measures. In early September 2026, Estonia implemented strict digital restrictions, with state and government institutions refusing electronic mail sent directly from Russian servers or ‘.ru’ domains. Minister of Justice and Digital Affairs Liisa Pakostová noted that cyberattacks against Estonia have increased exponentially since 2022, with a majority linked to Russia.

By late September, the friction shifted to the physical border. The Russian Federal Security Service (FSB) implemented temporary restrictions along a five-kilometer strip of the border in the Leningrad region, specifically affecting the Kingisepp and Slantsy districts. Effective from September 16 to September 26, 2026, these measures include a nighttime curfew for individuals and vehicles outside populated areas, as well as prohibitions on hunting, carrying firearms, and accessing riverbanks. On the Narva River, between the Bolshaya Cheremukha and Kriusha rivers, the use of small boats is restricted.

The FSB officially stated these actions are intended to prevent border and migration violations and to protect aquatic biological resources. While Estonian authorities were aware of the upcoming restrictions, they noted they received no direct notification from the Russian side. Although Tallinn does not currently view the restrictions as an extraordinary emergency, the Estonian government is preparing for the potential rapid closure of border crossings. Analysts suggest the measures may serve as a barrier to prevent Russian citizens of conscription age from fleeing the country.
