Iran's Zarif says Tehran will leave nuclear deal if necessary

Iran will leave its 2015 nuclear deal with world powers, Foreign Minister Mohammad Javad Zarif said on Monday, if Tehran's interests were not protected by other parties to the pact.

"Iran will leave its 2015 nuclear deal with powers if necessary," Zarif told a news conference broadcast live on state TV, "calling on Europeans to accelerate their efforts to shield Iran's economy from U.S. sanctions."
