Ukrainian Foreign Minister Dmytro Kuleba said he received a phone call from his Iranian counterpart Hossein Amir-Abdollahian on Friday and that he demanded Tehran to stop sending weapons to Russia.

"I demanded Iran to immediately cease the flow of weapons to Russia used to kill civilians and destroy critical infrastructure in Ukraine," Kuleba said in a tweet.

Amir-Abdollahian repeated Iran's denial of supplying weapons to Russia, Iranian state media reported.

"We have good ties with Russia and have had defense cooperation since earlier, but our policy towards the conflict in Ukraine is to respect the territorial integrity of countries, not to send weapons to conflicting parties," Amir-Abdollahian was quoted as saying.
