Iranian drones that were used in an attack on a Zodiac Maritime-operated MR tanker in 2021, are now being deployed in Ukraine, the US has warned.

The US Defense Intelligence Agency (DIA) made the claims in a detailed schematic analysis released Tuesday, with charts and pictures of debris documenting Russian use of unmanned aerial vehicles.

The report is said to provide a visual comparison of UAVs used by Russian forces in Ukraine and Iranian UAVs used to attack US and partner interests in the Middle East.
