Iranian and US naval ships are dangerously close to each other in the Strait of Hormuz, where the Iranian Navy is holding a military exercise. Iran has warned that it will close the Strait, used for exporting up to 40% of world oil exports, if any more sanctions are slapped on Iran.

The United States said for its part that it would not tolerate the closing of a major water route.

Right after this, the USS John Stennis with a group of escort ships appeared in the Strait.

Tehran has threatened with a military rebuff to the Yankees, if need be.
