Overnight Russia attacked sites in Odesa and Sumy, while Ukraine attacked 20 Russian vessels in the Black Sea.

Six people have been killed in Ukraine following an overnight Russian attacks on the Black Sea port of Odesa and the eastern city of Sumy, according to local officials. Governor of Odesa region Oleh Kiper said the "massive" drone and missile strike marked the fifth day in which Russia has attacked the region. Across the country, three people were killed and 17 injured in a "guided aerial bomb" attack on Sumy, the city's acting mayor, Artom Kobzar, said. Meanwhile, Ukraine's military said its drones hit 20 Russian vessels, including 17 oil tankers, in the Black Sea overnight. The Russian ministry of defence confirmed it had attacked Odsea, saying it had deliberately targeted port infrastructure, "used for the unloading of petroleum, oil, and lubricants". Writing on Telegram, Kiper accused Russia of deliberately targeting the civilian population and said residents were killed and injured when a Russian missile struck a multi-storey residential building. In its statement, Russia claimed to have targeted sites involved in the manufacture of military hardware, and the transport of cargo. Russia's attacks in recent days have targeted Ukraine's deep-water Black Sea ports in the wider Odesa area, which handle much of the country's grain and other cargo and are vital to its wartime economy.
