"The country's national and security interests necessitate that under no condition strangers and those who have done their best in animosity towards the Islamic Revolution and the sacred systems of the Islamic Republic of Iran be allowed to enter our military centers under any protocol or agreement under the name of inspection or access," Major General Firouzabadi said on Friday.

"All of us should be cautious about this red line," he added.

His remarks came after the Iranian Supreme Leader reiterated Iran's opposition to the inspection of sensitive military sites and interview with the country's nuclear scientists.
