(Reuters) - Honoring the 2015 nuclear deal is not Iran’s only option, Foreign Minister Mohammad Javad Zarif said on Thursday in a Twitter post.

Iran has remained within the main restrictions on its nuclear activities imposed by the deal with major powers, a confidential report by the U.N. atomic watchdog indicated on Thursday.

“Being the party to still honor the deal in deeds & not just words is not Iran’s only option,” Zarif wrote.
