Russian forces intensified their assault on Ukrainian cities, with Kyiv and Kharkiv bearing the brunt. Overnight drone attacks on Kyiv resulted in fires and injuries, while a KAB-guided bomb strike on Kharkiv's UNESCO-protected Derzhprom building killed four. As the day progressed, reports emerged of North Korean troops near Ukraine's border, with Zelensky estimating 3,000 at Russian training grounds. This development prompted Ukraine and South Korea to agree on intensified intelligence sharing. The Ukrainian parliament extended martial law and general mobilization, with plans to draft an additional 160,000 people. By afternoon, news broke of Zelensky's denied request for Tomahawk missiles from the US. The day concluded with reports of negotiations between Ukraine and Russia to halt strikes on energy infrastructure, though Ukrainian officials later denied these claims.
