Russia's Defense Ministry, meanwhile, said its forces downed at least 66 Ukrainian drones overnight into Tuesday morning. Among the areas targeted was the southwestern Voronezh region which borders northeastern Ukraine. At least 16 people were injured there, Gov. Aleksandr Gusev said on Telegram.

Ukrainians are tired, run down by the emotional toll of the invasion and the physical toll of sleepless nights due to air raid sirens, explosions and the screeching sounds of attack drones.

“The report is very murky and very inexact,” said Bjorn Fehrm, an aerospace engineer and analyst at aviation consultancy Leeham News and Analysis.
