SYDNEY, June 17 (Reuters) - Australia on Wednesday relaxed its travel advice for Bahrain, Israel, Kuwait, Qatar and the United Arab Emirates after the U.S. and Iran reached an interim deal to end the war in the Middle East. Foreign Minister Penny Wong said the advisory moved to "reconsider your need to travel" from "do not travel," but added that Australians should continue to delay non-essential travel to the Gulf states.
