Russia launched one of its heaviest aerial assaults this year on the night of 20–21 August, firing 574 drones and 40 cruise and ballistic missiles at targets across Ukraine, the Ukrainian Air Force said. Air-defence units reported downing the majority of the incoming weapons, yet impacts were recorded in at least 11 locations, mainly in the country’s west. Two missiles struck a consumer-electronics plant owned by U.S. manufacturer Flex Ltd. in Mukachevo, 16 miles from the Hungarian border, igniting a large fire while some 600 night-shift workers were on site. Local officials said at least six employees were wounded. Elsewhere, cluster-munitions hit residential districts of Lviv, killing one person and injuring several others; overall casualty tallies from regional authorities indicated roughly 15–19 people wounded nationwide. Kyiv described the barrage—its largest since mid-July—as a ‘massive combined air strike’ on civilian and energy infrastructure. President Volodymyr Zelenskyy argued the attack on an American investment underscored Moscow’s lack of interest in ongoing U.S.-led peace efforts and urged partners to tighten sanctions and other pressure on the Kremlin.
