Ukrainian media published footage of a strike by Ukrainian Storm Shadow cruise missiles, made in England, on a building in the village of Maryino in the Kursk region of Russia. The strike was carried out on buildings on the territory of the estate of the princes Baryatinsky, it is unknown what is there. According to Ukrainian media, there is a communications bunker under the building. The second version of the media is that there were North Korean soldiers in the bunker. Judging by the video, there is no air defense in the area. Or the air defense is not equipped with radar to detect low-flying targets, this happens quite often. Why is this happening, the length of the front line is about 2000 km, the Russian army does not have enough air defense systems to cover all the facilities in Russia, since there are thousands of them. It is worth noting that no air defense can shoot down 100% of targets. Earlier, it was proposed to create an air defense belt around Ukraine, but it is unknown whether this was implemented. The video was filmed by a Ukrainian drone on November 20 and shortened. Judging by the video, about 10 missiles reached their target. At the end, the results of the missile strike are shown, but it is difficult to understand anything from them.
