Kidnapped American journalist Peter Theo Curtis is released, days after the murder of James Foley

American journalist Peter Theo Curtis is free, after being held for nearly two years by Muslim extremists in Syria. His release by the militant group the Nusra Front came as a surprise, just days after the execution of fellow American journalist James Foley by ISIS. Miguel Marquez has more about Curtis' ordeal.
