Iranian troops are personally present in Russian-annexed Crimea to keep the Shahed-136 drones operational. This is written by AP with reference to its correspondent in the White House.
Pentagon spokesman John Kirby claims that Iran sent a "relatively small number" of personnel to the peninsula. According to him, the Iranian military is engaged in briefing and technical support, and the direct piloting of drones lies with the Russians.
According to the British government, members of the Islamic Revolutionary Guard Corps were sent to assist the Russian military – the organization is recognized as a terrorist organization in the United States. This was also reported by the Institute for the Study of War (ISW). Prior to this, The New York Times, citing US officials, wrote that the Iranian military is far from the front line.
Earlier, the EU and the UK imposed sanctions on Iran over the supply of drones to Russia. The EU has imposed sanctions directly on Shahed Aviation Industries.
