Anatoly Antonov, Russia's Ambassador to the United States, stated on Thursday that he was not permitted to speak at the Organization of American States (OAS) meeting during which a vote was held to suspend Russia's status as a permanent observer.

Antonov stated that "during the special meeting on this topic, Russia as the permanent observer to the Organization was denied the opportunity to speak at the meeting either before or after voting on the document."

According to Antonov, the OAS' decision to suspend Russia is a "grave mistake", and added that the "task of any international structure is to unite states in solving urgent problems, which are more than enough in the region."

Days ago, Antonov accused Washington of stealing Moscow's money in relation to sanctions, including freezing the Russian central bank's assets in the West.
