Russian missile and drone attacks on Kyiv early Thursday left six people dead and more than 50 injured, according to Ukrainian authorities, marking one of the most severe assaults on the capital in recent weeks.

Among the fatalities was a six-year-old boy, officials said. Three deaths occurred at the site of a collapsed apartment building in the Solomyansky district, where rescue workers continued to search the rubble for survivors. Ukrainian emergency services warned the death toll could rise as efforts to locate those trapped under debris continued.

Kyiv officials reported damage at over 20 locations across the city, including residential buildings, a hospital, a school, and a kindergarten. Tymur Tkachenko, who leads the city’s military administration, called the scope of destruction “extensive” and said search operations would continue throughout the day.

Interior Minister Ihor Klymenko confirmed that one of the missiles struck a multi-story residential complex, destroying an entire section of the building. Emergency responders said dozens were hospitalized, with injuries ranging from cuts caused by shattered glass to severe trauma from the blasts.

Two districts, Sviatoshynsky and Solomyansky, were hit hardest. In Shevchenkivsky, a children’s hospital ward suffered structural damage when the shockwave from a nearby explosion blew out its windows. No injuries were reported inside the facility.

In a statement on social media, Kyiv Mayor Vitali Klitschko called the situation “critical,” and urged residents to seek shelter during future air raid alerts. Several city schools also sustained damage, further delaying the start of the academic year for many students.

The strikes come at a time of increased international pressure on Moscow. Earlier this month, former U.S. President Donald Trump issued an ultimatum to Russian President Vladimir Putin, demanding a ceasefire agreement within 50 days or face heightened economic sanctions. On Monday, Trump shortened that deadline to approximately 10 days, expressing frustration over Russia’s continued military operations in Ukraine.

Speaking from London, Trump said he had anticipated progress toward a ceasefire, based on private discussions with Putin. However, he noted that the ongoing missile attacks were inconsistent with the tone of those conversations. While he stopped short of accusing Putin of lying, he acknowledged a widening gap between diplomatic assurances and battlefield realities.

Ukrainian officials echoed those concerns. Foreign Minister Andrii Sybiha characterized the attacks as a “brutal message” and called on the U.S. and its allies to escalate pressure on the Kremlin. He emphasized that several civilians remained trapped under debris and accused Moscow of deliberately targeting residential areas.

The Kremlin has not commented publicly on the latest wave of strikes.
