@foxnews: Iran is raising the stakes around the Strait of Hormuz, warning ships they could face sanctions if they enter a new restricted exclusion zone outside the critical waterway. The announcement comes after the U.S. launched strikes on three Iranian oil tankers, which followed Iran firing ballistic missiles at two U.S. Navy warships. U.S. officials say commercial ships are still being escorted through the strait as more than 20 American warships maintain a blockade of Iranian ports.
