KYIV/WASHINGTON – The United States said Thursday that Iranian military trainers had been sent to Crimea to assist Russian forces using Iranian-made drones to attack targets in Ukraine, adding a new international element to a war that has already worsened some geopolitical tensions. Ukrainian citizens endured the first day of nationwide scheduled power outages since the war began eight months ago so repairs could be made to damaged or destroyed energy plants as winter approaches.

Iran has sent trainers to occupied Ukraine to help Russians overcome problems with the fleet of drones that they purchased from Tehran, according to current and former U.S. officials briefed on the classified intelligence, a further signal of the growing closeness between Iran and Russia since Moscow's invasion of Ukraine. The Iranian trainers are operating from a Russian military base in Crimea where many of the drones have been based since being delivered from Iran. The trainers are from the Islamic Revolutionary Guards Corps, a branch of the Iranian military designated as a terrorist organization by the United States. In recent days, the Iranian drones have become an important weapon for Russia, which has used them as part of the broad strikes across Ukraine against electrical infrastructure and other civilian targets. The deployment of the Iranian trainers appears to coincide with the stepped-up use of the drones in Ukraine and indicates a deeper involvement by Iran in the war.
