"On Jan. 5, a high-level Iranian delegation visited the Russian town of Yelabuga, about 600 miles east of Moscow. Iran and Russia have ambitious plans to build a large factory there that will manufacture at least 6,000 drones based on Iranian designs. Iran has already supplied Russia with hundreds of Shahed-131/136 loitering munitions – single-use, self-detonating drones – for the war against Ukraine."

"American defense officials on Tuesday sought to dispel any doubt that Iran is supplying drones for Russia’s war in Ukraine, releasing photos and analysis of unmanned aircraft deployed in the conflict to demonstrate Tehran’s involvement.
During a briefing in London, analysts from the Defense Intelligence Agency displayed photos of drones that attacked Ukraine alongside images of those previously traced to Iran. A comparison of design details such as tail fins, nose cones and landing gear shows that the weapons used in Ukraine are “indistinguishable” from Shahed-131 and -136 attack drones and Mohajer 6 unmanned aerial vehicles used in the Middle East."
