Urban combat continues in Kostiantynivka as ZNPP suffers 19th blackout

Ukrainian forces are engaged in urban combat within Kostiantynivka against enemy infiltrators, with a battalion commander indicating the city is "semi-encircled" due to Russian advances. Military experts suggest Kostiantynivka could be lost in the coming months as the situation sharply worsened in June. Separately, the Zaporizhzhia Nuclear Power Plant experienced its 19th complete loss of external power on June 10, around 9 PM, following an attack on an electrical substation, necessitating reliance on backup diesel generators, as confirmed by the IAEA. On June 12, the General Staff reported 193 combat engagements across the front, including 61 air strikes, 193 guided aerial bombs, 6,186 drone attacks, and 2,341 shelling incidents. Russian President Vladimir Putin announced Russia would intensify strikes on Ukrainian infrastructure in response to recent Ukrainian attacks on Russian oil refineries.
