More than 10,000 American troops are helping enforce the blockade on Iranian ports, and while no ships have yet been boarded, the U.S. military said Thursday that it is warning Iran-linked ships that it could fire warning shots or escalate to other force if they try to outrun the Navy.
Thirteen vessels have turned around rather than confront a naval blockade that began earlier this week, Gen. Dan Caine, chairman of the Joint Chiefs of Staff, told reporters at the Pentagon.
