"Iran's military capabilities, including access to ballistic missiles, are no bargaining chip or agenda," Brigadier General Sanayee Raad told FNA on Saturday.

He reiterated that supporting the nuclear negotiating team does not mean accepting all conditions of the other side, and said, " Negotiations between Iran and the Group 5+1 (the US, Russia, China, France and Britain plus Germany) will be merely confined to nuclear issues."

Iranian officials have on different occasions underscored that the country's missile program is non-negotiable, stressing that the talks with the six world powers are limited to the nuclear issue.

In relevant remarks in March, Commander of the IRGC Aerospace Force Brigadier General Amir Ali Hajizadeh underlined that the Islamic Republic of Iran would never accept negotiating its ballistic missiles and other defense capabilities with the world powers.

"The Islamic Republic of Iran's nation, government and Armed Forces all believe that the country's defensive capabilities, especially the ballistic missiles, will never be negotiable at all. This is a message which should be understood by the bullying powers which raise excessive demands," Hajizadeh said, addressing a ceremony to unveil a new long-range ground-to-ground cruise missile system, named 'Soumar', in Tehran on March 8.

He downplayed the effects of sanctions on Iran's defensive programs, and said the Soumar missile system unveiling ceremony had this message for the country's opponents that such hi-tech products and capabilities are developed and produced in large numbers, while Iran is under the toughest "sanctions that are described by the enemies as harsh and bitter".

Iran and the six world powers struck a deal in Vienna on Tuesday.
