Ukrainian forces engage in Kostiantynivka urban combat, ZNPP loses external power, and refinery strikes reported

Ukrainian forces are engaged in urban combat in Kostiantynivka against infiltrating enemy personnel. The Zaporizhzhia Nuclear Power Plant experienced its 19th loss of external power, and Ukraine reported strikes on multiple Russian oil refineries.

Ukrainian forces are engaged in urban combat in Kostiantynivka against infiltrating enemy personnel, with assault units conducting clearing operations. A battalion commander described the city as "semi-encircled" following Russian advances near Chasiv Yar and Berestky. Reports indicate over a hundred Russian personnel have infiltrated, with some observed in the city center.

Separately, the Zaporizhzhia Nuclear Power Plant (ZNPP) experienced its 19th loss of external power on June 10, around 9 PM, after an attack on an electrical substation, leading it to rely on backup diesel generators, a situation confirmed by the IAEA.

Ukraine's General Staff confirmed striking the Afipsky oil refinery in Russia's Krasnodar Krai, reporting damage and a fire. Additionally, Ukrainian Defense Forces reportedly struck the "TANEKO" and "TAIF-NK" oil refineries in Nizhnekamsk, Tatarstan, on June 12, with hits and fires confirmed.
