A U.S. Navy ship has rescued the crew of an Iranian fishing vessel from pirates. The Iranians had apparently been held for weeks. The U.S. ship, part of the USS Stennis carrier battle group, took some 15 pirates prisoner. The Stennis is the same ship that Iran threatened just a few days ago as it transited out of the Persian Gulf. Robert Siegel talks to NPR Pentagon correspondent Tom Bowman for the latest.
