Ukraine's military launched what has been described as the largest drone assault on Russian territory since March.

Russian air defense systems shot down 105 Ukrainian drones overnight on May 22, including 35 intercepted over Moscow Oblast, the Russian Defense Ministry claimed. Moscow Mayor Sergei Sobyanin said that all the drones were flying toward the Russian capital.

All four airports in greater Moscow suspended operations multiple times over the past day, resuming around 6 a.m. Thursday, according to a flight safety watchdog

Ukraine's 425th separate assault regiment said its troops trained "hundreds of hours" to shoot small arms from atop speeding off-road bikes.
