More Red Sea shipments disrupted as Rubio says Iran not serious about talks

By Jana Choukeir, Elwely Elwelly and Michael Martina DUBAI/MANILA, July 22 (Reuters) - U.S. Secretary of State Marco Rubio said on Wednesday that Iran is not serious about talks to end their war, as the widening conflict disrupted two of the world's most critical energy chokepoints. Four tankers carrying Saudi crude to Asia reversed course in the Red Sea on Wednesday, a day after three others had done so, following threats to block Saudi shipping from Yemen's Iran-aligned Houthis, who control the coast on the southern route out.
