Urban combat continues in Kostiantynivka amid broader conflict developments

Ukrainian forces are engaged in urban combat in Kostiantynivka against enemy personnel, with assault units conducting clearing operations. A battalion commander noted the city is "semi-encircled" due to Russian advances near Chasiv Yar and Berestky. President Zelenskyy stated Ukraine's Unmanned Systems Forces have hit Russian targets valued at nearly $40 billion in their first year, improving logistics targeting in occupied territories. On June 10, Russian forces attacked two civilian cargo vessels, flying Panamanian and Barbadian flags, in the Black Sea. One vessel experienced a fire, which was extinguished, while the other was carrying wheat; both remained seaworthy and continued their routes. Russian forces also targeted the southern Odesa region. Separately, Ukrainian forces reportedly struck a military factory in Cheboksary and the Kuibyshev oil refinery in Russia's Samara region using missiles and drones on June 10.
