The United Nations has expressed grave concern over a 'dangerous escalation' in the ongoing conflict in Ukraine, particularly following a series of severe missile and drone attacks on Kyiv. Volker Turk, the UN rights chief, urged both Russia and Ukraine to return to the negotiating table to prevent further suffering. In the first four months of 2026, the UN reported 815 civilian deaths and 4,174 injuries, a 21% increase from the same period last year. Turk highlighted the need for both parties to adhere to international humanitarian law, which obligates them to take all feasible precautions to protect civilians. He also condemned recent threats from Russian officials to intensify attacks on Kyiv. Additionally, the UN's review of information regarding a Ukrainian strike on an educational complex in Starobilsk revealed civilian casualties, including students. Turk called for independent investigations into these incidents to hold those responsible accountable.
