TEHRAN (Press Shia) – Iranian Foreign Minister Mohammad Javad Zarif said the Islamic Republic has remained fully committed to its obligations under the 2015 nuclear deal between Tehran and world powers, also known as the Joint Comprehensive Plan of Action (JCPOA).

“Iran – unlike the US – has complied in good faith with the letter AND spirit of JCPOA.  Rhetoric & actions from US show bad faith,” Zarif said on his official Twitter account on Friday.  

In a follow-up message, he added, “Every word of JCPOA carefully negotiated. Iran does not develop missiles that are 'DESIGNED to be capable of delivering nuclear weapons'”.

The Iranian minister further stressed that Iran has never been and would not be developing nuclear weapons, saying, “So, by definition cannot develop anything designed to be capable of delivering them.”

It came after the Imam Khomeini National Space Center was officially inaugurated in Iran on Thursday with the successful test-launch of a homegrown satellite carrier dubbed Simorgh.

US State Department spokeswoman Heather Nauert claimed on Thursday that the rocket launch violated United Nations Security Council Resolution 2231.

She called Iran's rocket launch a "provocative action" that violated the "spirit" of the JCPOA.

Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) reached the 159-page nuclear agreement in July 2015 and implemented it in January 2016.

Since the historic deal was signed in Vienna, the IAEA has repeatedly confirmed the Islamic Republic’s compliance with its commitments under the JCPOA, but some other parties, especially the US, have failed to live up to their undertakings.
