Explosions were reported at Russia's port of Novorossiysk, a major hub on the Black Sea for Russian oil exports. Russia's Defense Ministry says the port was attacked by unmanned Ukrainian sea drones, and ship movement at the port was temporarily halted, according to emergency workers and pipeline services cited by Reuters.
Videos posted to social media show a large Russian ship listing to one side while being towed back to port. Kyiv has not yet made any official comment.
Russian opposition leader Alexei Navalny was sentenced on Friday to 19 more years in prison after being found guilty of a series of charges his supporters say are politically motivated.
Meanwhile, international leaders continue to urge Russia to return to the Black Sea grain deal, with U.S. Secretary of State Antony Blinken calling on Moscow to end its "blackmail" over global food supplies. Since Russia's withdrawal from the humanitarian initiative in July, it has launched attacks on several Ukrainian ports holding grain supplies set for export, and damaged or destroyed food storage and export infrastructure.
