Kyiv has been furious at Iran for allegedly supplying Iranian drones to Russia, Mikhail Podolyak, adviser to the head of the Office of the President of Ukraine, noted.

According to him, Iran "decided to support the killing of Ukrainians by transferring modern drones to Russia."

"Years of sanctions, isolation, disgusting reputation and ultimate strategic nullification have never given Iran a chance to figure out how to rise from the bottom of civilization," he tweeted.

The Ukrainian Foreign Ministry has decided to strip the Iranian ambassador of his accreditation, as well as significantly reduce the number of diplomatic staff at the embassy. "It was stated to the Iranian side that the supply of Iranian weapons to Russia for their subsequent use by Russian troops against the Ukrainian civilian population and the Defense Forces directly contradicts the publicly declared position of neutrality, respect for the sovereignty and territorial integrity of Ukraine," the Ukrainian Foreign Ministry said.

Prior to the Foreign Ministry's decision, President Volodymyr Zelenskiy said that "the Russian army used Iranian drones for its strikes. The world will know about every case of cooperation with evil, and it will have appropriate consequences." He instructed the Foreign Ministry to respond. 

Tehran has not yet responded to Kyiv latest demarche.
