UN Secretary-General Antonio Guterres condemned both Russia and Ukraine for attacks on civilian areas amid escalating conflict in Ukraine and called for an immediate ceasefire on August 6, 2026 [1, 2, 3]. Guterres urged urgent de-escalation, warning that attacks on civilians and civilian infrastructure violate international humanitarian law and must stop immediately, with UN Deputy Spokesman Farhan Haq stating, "Attacks against civilians and civilian infrastructure are a clear violation of international humanitarian law, and must stop immediately" [3].

In the nights of August 4-5, Russian forces launched large-scale missile and drone strikes on Kyiv and surrounding areas, killing at least 17 civilians and injuring dozens more, including attacks on a train station in the Brovary district [4]. The strikes caused damage to residential buildings, schools, public transport, water systems, and humanitarian warehouses in cities including Kramatorsk, Kherson, and Zaporizhzhia [4]. On August 6, Russia also hit a commercial ship carrying Ukrainian wheat in the Black Sea and launched missile attacks on other Ukrainian sites [1].

Ukraine responded with drone strikes targeting Russian oil refineries in the Bashkortostan and Yaroslavl regions, located roughly 700 to 1300 kilometers from the front lines [1]. Russian defense forces reported downing over 600 Ukrainian drones overnight, including 92 in the Yaroslavl region alone [1].

The UN's Ukrainian human rights monitoring mission reported 1,396 civilian deaths and 7,978 injuries in Ukraine during the first half of 2026, a 37% increase compared to 2025. Most casualties resulted from Russian long-range missile and drone attacks on cities far from the front lines [4].

The UN also expressed concern about maritime security risks in the Black Sea and Sea of Azov, warning disruptions could impact global food supplies due to attacks on commercial vessels [3]. Ukraine’s President Volodymyr Zelensky said, "Russia must choose peace," echoing the call for cessation of hostilities [1].

The UN Secretary-General called for a just, sustainable, and comprehensive peace in line with international law, including the UN Charter and relevant resolutions [3]. The escalating attacks and civilian toll highlight the urgency of the UN’s pleas for a full, immediate, and unconditional ceasefire.
