Description:Iran is now charging that the presence of a U.S. drone in its air space was a clear breach of international law, and it plans to pursue a case against the United States in international bodies. On December 4th, Iran announced it had downed the unmanned spy plane in the eastern part of the country, near Afghanistan. It has since shown images of the apparently intact drone on television, and said its scientists are close to cracking the drone's technological secrets.(1:20)
