UPDATE 1-U.S. grants visa to Iran's Zarif for UN meeting this week -sources

The United States has granted a visa to Iranian Foreign Minister Mohammad Javad Zarif to attend a U.N. meeting in New York this week, two sources familiar with the matter said on Sunday, saying Secretary of State Mike Pompeo had approved the decision. Had Pompeo not approved giving a visa to Zarif, Iran's top diplomat and nuclear negotiator, it could have been a signal that the United States was trying to further isolate the Islamic Republic and perhaps closing the door to diplomacy.
