Ukraine accused Russia of attacking its vessels in the Black Sea near Crimea on Sunday, killing several sailors and sparking international condemnation. The US, UK, and EU all condemned Russia’s actions, as did Turkey and the UN Security Council. The incident has once again caused a heated exchange of accusations between the two sides, with both Russia and Ukraine vowing to respond if further incursions take place. This latest escalation is likely to worsen the already strained relations between Russia and the West.
