Rubio says US still willing to negotiate over Iran crisis

DUBAI/MANILA, July 22 (Reuters) - U.S. Secretary of State Marco Rubio said on Wednesday the United States is still willing to negotiate an end to the Iran crisis but Tehran is not serious about talks, as the widening conflict disrupted two of the world's most critical energy chokepoints. Rubio made his comments in a meeting of Southeast Asian foreign ministers a day after three oil tankers carrying Saudi crude to Asia reversed course in the Red Sea, apparently in response to threats from Yemen's Iran-aligned Houthis.
