A U.S. stealth drone that crashed in Iran last week was part of a CIA reconnaissance mission which involved both the intelligence community and military personnel stationed in Afghanistan, two U.S. officials confirmed to CNN Tuesday.

The officials said they did not believe the mission involved flying the aircraft directly over Iran because the reconnaissance capability of the RQ-170 Sentinel drone would allow it to gather information from inside Iran while remaining on the Afghanistan side of the border. The officials also for the first time confirmed to CNN it was an RQ-170 drone that was lost.

A third U.S. official confirmed that when the drone crashed, the United States briefly considered all potential options for retrieving the aircraft or bombing the wreckage, but those ideas were quickly discarded as impractical. There was also satellite surveillance over the site, which helped confirm the location of the wreckage before the Iranians retrieved it.
