US Senator Cory Booker expressed concerns about growing cooperation between Tehran and Moscow amid the Russian invasion of Ukraine. 

Talking to Iran International’s correspondent Arash Aalaei on Wednesday, the New Jersey Democrat said, "I have concerns about Iran's actions in numerous parts of the globe, and it is something my team and I work very hard on, and we take very seriously."

Noting that Congress is working on some measures to stop the Russo-Iranian axis in the Ukraine war, Booker said, "We are already making a lot of efforts. The (Senate Foreign Relations) Committee has taken bipartisan stands and will continue to do what is necessary to check the Iranian Russian and terrorist activities." 

US National Security Adviser Jake Sullivan warned twice in July that Moscow appears to be looking at buying Iranian drones and Russian officers even visited a drone base in Iran’s Kashan to review their options. 

An adviser to President Volodymyr Zelensky told Iran International on July 25 that Russia and Iran are allies in the Ukraine war and it won’t be a surprise if Tehran supplies drones to Moscow.

On July 26, an Iranian lawmaker confirmed Russia’s request to buy Iranian drones. On the same day, Iranian Civil Aviation Organization announced that Iran and Russia have signed a new agreement to expand cooperation in the aviation sector. 

On Wednesday, a top official was quoted by Russia's RIA news agency as saying that Iran will soon start accepting payments made with Russia's Mir bank cards, making it the latest country to adopt the Russian-made alternative to Visa and Mastercard.
