Ukraine launched drone strikes on Russia’s Baltic coast early on Sunday, damaging energy infrastructure near the Finnish border and forcing changes to civilian air routes across northern Europe.
The attack targeted the oil port of Primorsk, known in Finland as Koivisto, located on the Gulf of Finland between St Petersburg and the Finnish frontier. The site stands less than 50 kilometres from Finland at its closest point and serves as one of Russia’s main oil export hubs on the Baltic Sea.
