Iran said in a letter to the United Nations on Thursday that it is determined to go ahead with its disputed ballistic missile program, according to a copy of the letter tweeted by Foreign Minister Mohammad Javad Zarif.
"Iran is determined to resolutely continue its activities related to ballistic missiles and space launch vehicles," Iran's UN envoy Majid Takhte Ravanchi wrote in the letter.
The British, German and French ambassadors called on UN Secretary-General Antonio Guterres in a letter on Wednesday to inform the Security Council in his next report that Iran's missile program was "inconsistent" with a UN resolution that had endorsed the nuclear deal reached between Iran and six world powers.
