U.S. military blockade of Iranian ports begins

President Trump says the American military blockade of Iranian ports has begun. The blockade is underway as part of the president’s effort to force Iran to open the strait of Hormuz. All of this comes following a failure over the weekend by the U-S and Iran to reach an agreement to end the war that has gone on for more than six weeks. In the meantime, a fragile ceasefire remains in place.
