Drone incidents cause injuries and destruction in Russia and Ukraine.

A drone crashed into a residential building in Russia's Voronezh city, injuring three people. The incident is the latest in a series of drone attacks targeting Russian cities in recent weeks. The attacks have exposed breaches in Russian air defenses and porous border security. Ukraine has been intensifying its efforts to expel Russian forces from a vast swath of southern and eastern Ukraine that they invaded more than 15 months ago on orders from President Vladimir Putin. Ukrainian authorities have kept quiet about their latest military moves, refusing to join in on rising commentary from Western military experts and others that a long-anticipated counteroffensive was underway.
