Drone Warfare Escalates Between Russia and Ukraine.

Three drones were brought down outside a Russian army base in the village of Kalininets, located 60km southwest of Moscow. The Russian Defense Ministry called it an "act of terrorism" carried out by Ukraine. No one was injured in the incident, and the drone debris is being inspected. This is the latest in a string of drone attacks near the Russian capital in recent weeks, and Russian authorities have become increasingly preoccupied with drones following the May 3 attack on the Kremlin, which they call an attempted assassination by Kyiv on Putin.
