Iranian, Ukrainian experts meet to discuss Russia’s use of Iranian drones.

“Ukraine has informed Iran that the consequences of complicity in the Russian aggression will be incommensurable with the potential benefits of cooperation with Russia,” Oleh Nikolenko, a spokesman for Ukraine's Foreign Ministry, told CNN. 

A spokesperson for the Iranian Mission to the UN previously told CNN that a request had been made for a “joint meeting of experts” to look into the accusations. 

The Washington Post reported on Nov. 19, citing intelligence, that Iran and Russia had “quietly” reached an agreement to assemble “hundreds of unmanned weaponized aircraft” on Russian territory. 

Russia has been using Iranian-made Shahed-136 kamikaze drones against Ukraine since September, launching waves of attacks that killed civilians and destroyed energy facilities nationwide.
