WASHINGTON, - U.S. Secretary of State Mike Pompeo will not meet with his Iranian counterpart during a meeting of southeast Asian nations in Singapore at the weekend, a senior State Department official said on Tuesday a day after US President Donald Trump offered talks with Tehran without preconditions. 'Iran is not a member of any the multilateral gatherings so there are no plans for any engagement with Iran,' the senior official told reporters to preview Pompeo's visit to Singapore, Indonesia and Malaysia.
