TEHRAN, Oct. 7 (Xinhua) -- Iranian jet fighters have forced a U.S. warplane to land in one of Iran's airports after it entered Iran's air space without permission, the semi-official Fars News Agency reported on Tuesday.

    The U.S. warplane has eight passengers, including five high ranking generals and three civilians, Fars said without specifying when the incident happened.

    According to the report, the U.S. warplane incursion was found unintentional after one day's interrogation in the airport and was let fly to Afghanistan which was claimed as its destination.

    The report has not been confirmed by neither Iranian nor American military officials.
