Ukraine reports continued drone attacks and worsening situation in Kostiantynivka

Ukrainian forces reported intercepting or suppressing 110 out of 118 Russian uncrewed aerial vehicles launched overnight on June 13. Three drones struck targets, with debris falling in six locations. Separately, the General Staff detailed 193 combat engagements on June 12, including 61 air strikes and over 6,000 drone attacks. In Kostiantynivka, urban combat continues as enemy personnel have infiltrated the city, with assault units engaged. A battalion commander described the city as "semi-encircled" due to Russian advances near Chasiv Yar and Berestky. Military experts suggest the situation has "sharply worsened" in June, with one expert stating, "it seems that during June-July Kostiantynivka will be lost by Ukraine." The Zaporizhzhia Nuclear Power Plant experienced its 19th complete loss of external power on June 10, following an attack on an electrical substation, necessitating backup diesel generators, as confirmed by the IAEA.
