Ukraine’s government and Western intelligence agencies say Russia has been using Iranian-made Shahed-136 drones in the conflict since autumn last year. Also called the Geranium-2 by Russia, it has explosives in a warhead on its nose and is designed to loiter over a target until it is instructed to attack. Russia is planning to “exhaust” Ukraine with attacks using Iranian-made drones, Iran’s government says it supplied “a small number” of drones to Russia before the war. How hard is it for Ukraine to protect itself against drone strikes ?
