"They (the westerners) have made some comments about defensive and missile issues, but Iran will not allow them to visit our military centers and interfere in decisions about the type of Iran's defensive weapons," Velayati said on Tuesday.
He, meantime, stressed that Iran will never hesitate about manufacturing different types of weapons except for the nuclear weapons that are under a religious ban based on the Fatwa of Supreme Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei and other Weapons of Mass Destruction (WMDs), including chemical weapons, which have never been used by Tehran.
"Missiles like Shahab, Sejjil and the like, have never been used for carrying nuclear warheads, and therefore, are not subject to the paragraphs of the Vienna draft agreement," Velayati added.
