In a significant escalation of hostilities, Russian forces launched an extensive drone and missile assault on the Ukrainian capital, Kyiv, overnight. This attack, described by Mayor Vitaly Klitschko as the most massive to date, resulted in at least 20 fatalities, with around 90 people injured. The strikes targeted various locations across a wide area of the city, including an ambulance station, prompting Klitschko to declare Friday as a day of mourning. Notably, the barrage deployed the largest number of weapons on the capital, surpassing previous attacks in terms of scale and intensity. In response to Russia's allegations of striking military plants in retaliation for attacks on Russian civilian infrastructure, Ukraine accused Moscow of deliberately targeting civilian areas. Among the casualties were children, according to Tymur Tkachenko, head of Kyiv's military administration. As a result of the assault, 52,500 people, including 4,500 children, sought shelter in underground stations overnight - the highest number in recent years. The attack lasted over 11 hours and impacted various parts of the city, with some neighborhoods being evacuated. Ukrainian military experts described this latest barrage as one of the most challenging assaults for the country's air defences in recent months due to Russia's tactic of using multiple types of weapons within the same time window. This trend suggests a shift in Russia's attack patterns on Kyiv over the past two months, with attacks happening less frequently but lasting longer and seeming more widespread. In response to these attacks, Ukraine has urged its allies to send more air defence systems and has appealed to Washington for licences to manufacture Patriot defence missiles. The Russian assault also extended to military bases in central and eastern Ukraine, according to the ministry of defence. As global trends indicate a continued intensification of conflict, the international community must address these developments with urgency to safeguard peace and stability.
