A Ukrainian drone attack last week forced a refinery in Ryazan, southeast of Moscow, to suspend operations. Russia's Defense Ministry said in a statement on Friday that 49 Ukrainian drones had been downed over the country overnight, including 25 in the southern Rostov region and eight in the Volgograd region.

The Ukraine conflict is the first major drone war in military history. Despite tactical losses on several parts along the line of contact, the Ukrainian military has continued to maintain strategic pressure on Russia by targeting and attacking major targets behind enemy lines.
