( CNN ) -- Iran said Saturday that it downed and captured another `` enemy drone , '' the semi-official Fars News Agency reported . The incident reportedly took place during Iranian military maneuvers in southern Iran . `` IRGC 's electronic warfare systems detected electronic signals , which indicated that foreign drones intended to enter our country , '' said Islamic Revolutionary Guards Corps Lt. Gen. Hamid Sarkheili , Fars reported . `` Our specialist forces then succeeded in bringing down the drone in the field of maneuvers . '' Sarkheili said that Iran may release film of the drone . Earlier this month , Iran said that it had decoded and released footage from a U.S. drone that it downed more than a year ago . The black and white aerial footage , which Iran claims was from a RQ-170 spy plane , was aired by Iranian news agencies and placed on YouTube . Iran said it downed the drone on December 4 , 2011 , near Kashmar in the country 's northeast , some 225 kilometers ( 140 miles ) from the border with Afghanistan . At the time , U.S. officials acknowledged that the drone was missing and President Barack Obama asked Iran to return it . Iranian military officials vowed not to return the plane . In December 2012 , Iran 's navy claimed that it had captured another U.S. drone , after it entered Iranian airspace over the Persian Gulf . However , a U.S. defense official , who could not be named because the official was not authorized to speak to the media , told CNN that whatever the Iranians claim to have , it is not an actively operating U.S. Navy drone .
Incident reportedly took place during military maneuvers in southern Iran . It 's unclear exactly who the drone belongs to . Iran has claimed to have captured U.S. drones in the past .
