TEHRAN - Russia’s Air Force Commander in Chief Lieutenant General Viktor Bondarev arrived in Iran for talks with Iranian military officials to expand cooperation in missile systems, Press TV reported on Sunday.

During his stay in Iran, the Russian commander will meet with the Commander of Iran’s Khatam al-Anbiya Air Defense Base, Brigadier General Farzad Esmaili and the Commander of the Islamic Revolution Guards Corps Aerospace Division, Brigadier General Amir- Ali Hajizadeh.

Bondarev is making the four-day visit at the invitation of the commander of Iran Air Force, Brigadier General Hassan Shahsaf.Iran and Russia signed a contract on the S-300 defense system in 2007.

However, a UN resolution banned any supply of conventional weapons to Iran, including missile systems, tanks and warships, following which Russia canceled the S-300 shipment in September 2010.

Iran has been suing Moscow in the International Court of Arbitration for backing down on the contract, demanding 950 million U.S. dollars in compensation. (Xinhua)
