The Supreme Leader's Top Aide underlined that Iran will not allow access of foreigners to its sensitive military sites, state-run IRNA news agency reported.

"Iran will never let any foreigner have access to its military sites," Ali Akbar Velayati told reporters on Monday.

He noted that the visits (by foreigners) to the Islamic Republic's military sites are forbidden on the basis of the Leader's very specific viewpoints.

"We won't permit any stranger, either American or non-American, to visit the Islamic Republic's military and sensitive centers," he underlined.

His remarks came after Leader of the Islamic Revolution Grand Ayatollah Sayyed Ali Khamenei said in May that Iran will not allow the inspection of its military sites.

The Leader ruled out any request for interviews with Tehran's nuclear scientists, and described it as a kind of "interrogation".

"I would not let foreigners come (here) and talk to the Iranian nation’s beloved scientists... who have broadened this wide knowledge to this field," he added.

Iran and Group 5+1 (Russia, China, the US, Britain, France and Germany) have been negotiating to hammer out a lasting accord that would end more than a decade of impasse over Tehran's peaceful nuclear program.

On April 2, the two sides reached a draft nuclear agreement after more than a week of intensive negotiations in Lausanne, Switzerland, with both sides committed to push for a final, comprehensive accord until the end of June.
