Russia launched 250 drones and 14 ballistic missiles against Kyiv alone, Ukraine's air force said, causing fires in residential buildings. Two schools and a clinic were among the facilities hit in the Kyiv region. Zelensky said only "additional sanctions targeting key sectors of the Russian economy" could push Moscow to agree to a ceasefire. Last week, Russia said Ukraine had launched hundreds of exploding drones at the country, including strikes over Moscow. On Friday, Ukraine and Russia each handed over 390 soldiers and civilians in the biggest prisoner exchange since Russia launched its full-scale assault in February 2022.
