Ukraine's air defenses shot down 10 drones during an overnight attack on Kyiv from Russia, the country's military authorities said.
Kyiv Mayor Vitaliy Klitschko said there were no casualties, while the southern Odesa region also faced a barrage of drone attacks.
Ukraine's air defense forces say they took down a total of 23 drones across the Kyiv and Odesa regions.
Navalny is currently serving a nine-year sentence and could face up to 20 more on charges that his supporters say are purely political.
The Kremlin meanwhile may struggle to deal with more frequent attacks on its cities while continuing to refrain from fully mobilizing its population for war, the think tank Institute for the Study of War said in its daily report.
