Iran seizes cargo ship

"U.S. Navy ships will begin to accompany U.S. flagged commercial ships as they travel the Strait of Hormuz, a defense official confirmed to Fox News, on the heels of Iran seizing a cargo ship. 
The Obama administration is closely monitoring Iran's takeover of the ship, as it involved a Marshall Islands-flagged vessel. The Marshall Islands and the U.S. have a longstanding security agreement, and officials said Thursday the two nations are in contact. 
But, in a clear response to that incident, a defense official said the U.S. Navy will now accompany all U.S.-flagged ships going through the area. The move is the latest development in a high-stakes chess match in the region, with the Iran nuclear talks continuing to play out in the background." FOX
