Russia mounts biggest air attack on Ukraine ahead of prisoner swap

Russian forces launched their largest aerial attack of the war across Ukraine, killing at least 12 people, just hours before Russia and Ukraine completed a prisoner swap of 1,000 individuals. The assault involved nearly 370 drones and missiles, with most shot down. Residents took shelter in Kyiv's underground metro. The attack hit multiple regions including Kyiv, Mykolaiv, Ternopil, and Kharkiv. Ukrainian President Volodymyr Zelensky criticized the U.S. silence and called for new sanctions. The prisoner exchange, the largest since the war began, saw each side release 303 prisoners, with freed citizens celebrating.
