The Associated Press:

The United States military announced Thursday that it is conducting the 13th night of strikes against Iran as clashes escalate over shipping routes. Earlier Yemen’s Iran-backed Houthi rebels said they attacked two Saudi oil tankers in the Red Sea, potentially widening the Iran war as international oil topped US$100 a barrel.

US Central Command said the latest attacks are designed to “further degrade Iran’s ability to threaten civilian mariners and commercial vessels transiting regional waters” as the Americans push to regain control over the Strait of Hormuz and restore the flow of international shipping.
