DUBAI, July 21 (Reuters) - Two oil tankers carrying Saudi crude to Asia reversed course in the Red Sea on Tuesday after threats from Yemen's Iran-aligned Houthis, as a widening Middle East conflict disrupted shipping through two of the world's most critical energy chokepoints.
U.S. forces bombed targets in the south and west of Iran overnight, while Tehran targeted U.S. sites in Bahrain, Kuwait and Jordan and a tanker was hit in the Strait of Hormuz at the mouth of the Gulf.
