Secret underground drone base

Russia has been bombarding Ukraine with the drones and other weapons in attacks against Ukrainian energy and infrastructure sites. Ukraine believes Russia has used dozens of Iranian “kamikaze” drones in attacks on civilian targets, including in Kyiv. Iranian trainers are assisting Russia in the campaign out of a military base in Crimea, The New York Times reported, citing current and former US officials who had been briefed on classified intelligence. Many of the Iranian drones have been based in Crimea since they were delivered to Russia, the report said.
