Ukrainian drones have reportedly attacked targets in the Russian port city of Primorsk, located in the northern part of the Gulf of Finland in the Baltic Sea. Primorsk is one of Russia's most important crude oil export ports, and a fire has reportedly broken out, which has now been extinguished, according to the Reuters news agency. President Volodymyr Zelenskyj says that Ukrainian forces attacked two ships in the so-called Russian shadow fleet as they approached the Black Sea port city of Novorossiysk.
