Tehran, December 13 (KCNA) -- The deputy commander of the Islamic Revolution Guards Corps of Iran on Dec. 11 said that Iran will never send back the U.S. drone downed by it.

The U.S. drone's intrusion into Iran's airspace is a hostile act, he said, warning that Iran will take tougher corresponding steps in the future.

Iran cannot send the symbol of aggression back to those keen on gathering secret and important information related to the state security, he noted, adding that the capture of drone is Iran's victory as well as U.S. defeat in information and technological warfare.
