Ukraine faces intense combat as Russia vows to escalate strikes

Ukrainian forces are engaged in urban combat within Kostiantynivka against enemy infiltrators, with assault units conducting clearing operations. A battalion commander indicated the city is "semi-encircled" due to Russian advances near Chasiv Yar and Berestky. Military analysts suggest the city's situation has sharply escalated, with Russian forces now close to and operating within its districts, potentially leading to its loss in the coming months. 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. Concurrently, Russian President Vladimir Putin announced that Russia would intensify its strikes on Ukrainian infrastructure, following recent Ukrainian attacks on Russian oil refineries. The General Staff reported 193 combat engagements across the front on June 12, including 61 air strikes and thousands of drone and shelling incidents.
