Urban combat continues in Kostiantynivka as Zaporizhzhia NPP loses external power again

Ukrainian forces are engaged in urban combat within Kostiantynivka, deploying assault units to clear enemy personnel who have infiltrated the city. A battalion commander stated the city is "semi-encircled" due to Russian advances near Chasiv Yar and Berestky. Meanwhile, the Zaporizhzhia Nuclear Power Plant experienced its 19th loss of external power on June 10, around 9 PM, following an attack on an electrical substation. Energoatom confirmed the incident, noting the plant switched to backup diesel generators after the "ZaTES – Ferrosplavna №1" power line disconnected. Ukraine's General Staff reported 251 combat engagements on June 10, detailing 100 Russian air strikes and over 9,000 kamikaze drones. Commander-in-Chief Oleksandr Syrskyi stated Ukrainian drone units struck nearly 180,000 Russian targets in May, claiming a 1.5 to 1 advantage in FPV drones. Sources: Громадське, Радіо Свобода
