Ukraine launches one of its biggest drone attacks on Russia and Crimea

A senior political source from a second Nato member made a similar statement last week.

Power outages have continued to plague Sevastopol, the largest city in Russian-controlled Crimea, following repeated, intensified Ukrainian strikes on the peninsula.

But since the beginning of this year, after a string of devastating Russian drone strikes in northwestern Ukraine near the border with Belarus, President Volodymyr Zelensky has taken a more confrontational approach.

Ukrainian air defence forces have shot down or jammed three missiles and 174 of the drones.
