Over the course of August, Russia launched 4,216 air attack vehicles -- 4,060 attack or decoy drones and 156 missiles -- at a daily average rate of nearly 131 drones and five missiles, Ukraine's air force data showed. No night of August passed without a Russian attack, the Ukrainian government said.

President Volodymyr Zelenskiy will press for stronger pressure on Moscow as he meets allies in Denmark and France on Wednesday after Russian forces launched a sweeping air attack on Ukraine, damaging energy and transport infrastructure.
