IRNA � Access to Iran's military sites is a closed case, Iranian top security official said on Friday.

Secretary of Iran's Supreme National Security Council (SNSC) Ali Shamkhani made the remarks in reaction to calls for visiting Iranian military sites under the pretext of secret nuclear activity.

'Iran has no undeclared nuclear activity,' the official said referring to the UN nuclear watchdog reports which confirm peaceful nature of Iran nuclear program.

'Access to Iranian military sites is unnecessary,' Shamkhani said, noting that propagating Iranophobia is the aim of US and Zionist regime officials' claims.

'Any claim regarding Iran obligations in the Joint Comprehensive Plan of Action (JCPOA) should be studied in the International Atomic Energy Agency (IAEA) based on technical and legal considerations apart from the partisan views,' he noted.

Shamkhani said in the meantime that Islamic Republic would continue efforts for promotion of country's defensive power.

He called the US President Donald Trump policy towards Iran unconstructive and said, 'Islamic Republic will reciprocate US breach of its obligations enshrined in the nuclear deal.'
