Russia launched a massive attack on Ukraine overnight into Saturday with hundreds of drones, killing at least one person, part of a stepped-up bombing campaign that has dashed hopes for a breakthrough in efforts to end the more than 3-year-old war.

Ukrainian President Volodymyr Zelenskyy said Saturday morning that Russia had attacked Ukraine overnight with more than 300 drones and over 30 missiles. The strikes, which occurred Friday night into Saturday morning, affected the regions of Donetsk, Kirovohrad, Dnipro, Sumy, Kherson, Volyn, Zaporizhzhia, Mykolaiv, Odesa and Zhytomyr.

Russia has repeatedly shattered its own records for aerial assaults on Ukraine this summer, culminating in a peak attack on July 9 with the launch of 728 Shahed-type drones. Throughout the war, Russia steadily expanded the reach and intensity of its strikes on Ukrainian cities,
