 A sea drone attack damaged a Russian tanker near the strategic bridge linking Russia to the annexed peninsula of Crimea, Russian authorities said on August 5. Russian media said the SIG vessel, approaching the Kerch Strait linking the Black Sea and the Sea of Ozoff, was hit by Ukrainian drones. Ukraine's Interfax Agency, citing an unnamed Ukrainian security service source, also said Ukraine's navy was behind the attack with drones in its territorial waters. No one was hurt, but the Crimean Bridge and ferry transport were suspended for several hours, according to Russian-installed officials in Crimea, which Moscow seized from Ukraine in 2014. Kiev seldom claims responsibility for attacks inside Russia or on Russian-controlled territory in Ukraine, but has said that destroying Russia's military infrastructure boosts its counter-offensive chances in the 17-month-old war. The SIG had been supplying oil to Russian troops in Syria, according to Vladimir Bogov, a Russian-appointed official in Ukraine's southeastern region of Zaporizhia. The United States sanctioned the tanker and its owner, St. Petersburg-based trans-Petrichart, in 2019 for helping provide jet fuel in Syria.
