The Ukrainian military said it had struck Russia’s Ust-Luga oil terminal in the Leningrad region on Tuesday. The general staff said on Telegram it had preliminary confirmation of damage to three storage tanks belonging to the Transneft-Baltika company.

Crude oil exports from Russia’s Sheskharis terminal in the Black Sea port of Novorossiysk were suspended after a big drone attack and a fire, two sources told Reuters on Tuesday. The terminal, which typically loads 700,000 barrels a day of crude oil, is Russia’s key oil outlet in the Black Sea. Its suspension will add to the strain on Russian infrastructure, which has been repeatedly attacked.

Moscow’s troops targeted two buses in the eastern Dnipropetrovsk region, its governor, Oleksandr Ganzha, said on Telegram. A drone smashed into a bus approaching a stop in Nikopol’s city centre, he said, and later another bus was hit in a neighbouring community. Four people were killed in Nikopol and at least 16 injured, officials said. In the southern city of Kherson, a Russian attack on a residential area that lasted half an hour killed four elderly people and injured seven more, said the regional governor, Oleksandr Prokudin. Other deadly Russian strikes took place in Zaporizhzhia and Sumy oblasts, said Ukrainian officials.

Ukrainian drone strikes killed five civilians including a 12-year-old boy and his parents in Russia and Russian-occupied parts of Ukraine, Russian officials said on Tuesday. Reuters could not independently verify the officials’ statements, and Ukraine denies deliberately targeting civilians.
