Ukrainian forces in Kostiantynivka, drone strikes, and Black Sea vessel attacks

Ukrainian forces continue urban combat in Kostiantynivka against infiltrating enemy personnel, with assault units engaged in clearing operations. A battalion commander reported the city is "semi-encircled" due to Russian advances near Chasiv Yar and Berestky. Meanwhile, President Zelenskyy announced that Ukraine's Unmanned Systems Forces have, in their first year, struck Russian targets valued at nearly $40 billion, significantly enhancing logistics targeting in occupied territories. Separately, on June 10, Russian drones attacked two civilian cargo vessels, flying Panamanian and Barbadian flags, in the Black Sea. One vessel caught fire, which was extinguished, while the other was transporting wheat; both remained seaworthy. Russian forces also targeted the southern Odesa region.
