Russia has also started to launch fake drones, without any explosives, to confuse Ukraine’s air defence units and force them to waste ammunition. Compared to missiles they are much cheaper to build, easier to fire, and designed to sap morale.

Russia overnight launched a “record” 145 drones at Ukrainian territory, according to Ukraine’s air force, 62 of which were shot down. A further 67 were “lost,” the air force said, a likely reference to electronic jamming that caused the drones to veer off course.

Nov 10 (Reuters) - Ukraine launched at least 17 drones targeting Moscow early on Sunday, forcing the temporarily closure of two of the capital's airports, Russian officials said.
