Estonia’s foreign ministry announced on Monday that it summoned Russia’s charge d’affaires to formally protest a recent violation of its territorial waters by a Russian vessel.
Foreign Minister Margus Tsahkna stated on X that the incident involved an unauthorised Russian border guard vessel briefly entering Estonian waters by up to half a kilometre on Saturday.
According to the Estonian army, foreign warships are only permitted to sail through Estonian waters if they are conducting a peaceful passage and provide 48 hours’ advance notification to the foreign ministry, which the Russian vessel failed to do.
This marks the first time this year that a Russian ship has violated Estonia’s maritime border. The foreign ministry also noted that a Russian fighter jet had breached Estonian airspace in May.
Tensions between Estonia, a member of the European Union and NATO, and Russia have heightened since Russia invaded Ukraine in 2022, with Estonia being a staunch ally of Kyiv.
Russia has not had an ambassador in Tallinn since February 2023, following a reciprocal expulsion of envoys by both countries.
