Ukraine’s large-scale drone attack on Russian air bases thousands of miles behind the front lines is the latest in a long line of daring missions by Ukraine’s forces against its giant neighbor.

Russia’s Defense Ministry in a statement confirmed the attacks, saying they damaged aircraft and sparked fires on air bases in the Irkutsk region, as well as the Murmansk region in the north. It said strikes were also repelled in the Amur region in Russia’s Far East and in the western regions of Ivanovo and Ryazan, the ministry said.

The drone strikes on Russian air force bases weaken Moscow’s ability to wage war on its neighbor and undermine its capacity to threaten more distant rivals.
