Russia has sent a shipment of drones, including advanced models, to Iran to help counter potential joint attacks by the United States and Israel, according to US and European officials cited by the Associated Press this week. The drones were originally supplied by Tehran to Moscow after the start of the Ukraine war. The transfer marks a reversal in the flow of military technology between the two countries.

Following the February 28 US-Israeli strikes, Iran has carried out continuous drone attacks on Israel, its Gulf neighbors, and US bases across the Middle East for over a month. Although Iran possesses its own Shahed drones, Russia reportedly improved their design during the Ukraine conflict, adding enhanced navigation capabilities.

Officials said Russian and Iranian representatives held “very active” discussions this month about the drone transfer. However, it remains unclear whether the shipment is a one-time delivery or part of a larger series. The number of drones sent and the strategic significance of the transfer have not been disclosed, and Moscow’s motive for providing Tehran with advanced drones remains uncertain.
