TEHRAN (Tasnim) � Supreme Leader of the Islamic Revolution on Wednesday urged Iranian officials to take reciprocal measures should the other parties to last year�s nuclear deal known as the Joint Comprehensive Plan of Action (JCPOA), US in particular, fail to fulfill their commitments.

Addressing a gathering of officials responsible for holding the upcoming elections in Iran, Ayatollah Seyed Ali Khamenei called on the Iranian administration and members of the Committee for Monitoring the Implementation of JCPOA to beware of US deceits.

�The other side is a deceiver, do not trust its smile and mask,� the Leader warned, stressing that the current policies and objectives of the US are the same violent anti-Iran goals followed by Washington in the past.

�(Iranian) officials should make sure that the Americans do fulfill their commitments in the JCPOA implementation; otherwise, they surely should retaliate,� Imam Khamenei stressed.

In similar remarks on Tuesday, the Leader underscored that care should be taken to ensure the other side of the deal fulfills its commitments completely.

In a letter to Iranian President Hassan Rouhani, Ayatollah Khamenei reiterated his warning against deceptions and breaches of hegemonic states, US in particular, in this issue and other ones.

Elsewhere in his Wednesday remarks, Supreme Leader stressed that the JCPOA did not meet all of Iran�s demands, but it was still an �important and considerable� move that brought about this much of outcomes thanks to the country�s capabilities and opportunities.

The remarks came after Iran�s Foreign Minister Mohammad Javad Zarif and European Union�s Foreign Policy Chief Federica Mogherini on Saturday announced in a joint statement that the implementation of the nuclear deal finalized by Tehran and world powers back in July 2015 has officially been started.

With the implementation of the agreement reached between Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany), all nuclear-related sanctions against the Islamic Republic were terminated.
