Russia has been using drones and missiles to strike targets, wait some time, and then hit the same spot later.

Ukraine said it struck a Russian air base on Saturday, while Russia continued to attack Ukraine with hundreds of drones overnight as part of a stepped-up bombing campaign that has dashed hopes for a breakthrough in efforts to end the more than 3-year-old war.

Waves of drone and missile attacks targeted Kyiv overnight into Friday in the largest aerial attack since Russia's invasion of Ukraine began more than three years ago, injuring 23 people and inflicting severe damage across multiple districts of the capital in a seven-hour onslaught.
