Ukraine launched a wave of drone strikes on Sunday targeting Russian energy infrastructure, including the Baltic Sea port of Primorsk. Local governor Alexander Drozdenko reported that the attacks temporarily set the port on fire. Several other vessels in the Baltic Sea were also struck during the operation.
President Volodymyr Zelenskyy stated that the strikes also hit two tankers from Russia's shadow fleet near the Black Sea port of Novorossiysk. Ukraine alleges that these tankers were used illegally to transport Russian crude oil.
Zelenskyy said the attacks are designed to limit Russia's war potential. However, Kremlin spokesman Dmitry Peskov warned that global oil prices may rise further if Ukraine continues to target Russian oil infrastructure.
The strikes come as both sides continue to fire hundreds of drones at each other daily. Kyiv reported that Russia has stepped up its targeting of Ukrainian port infrastructure, using more than 800 drones in the first four months of 2026, which is more than ten times the number used during the same period a year ago.
