An Iranian military commander claimed Monday that the country has stolen all the secrets held by a high-tech American surveillance drone that crashed in Iran last year, according to Iranian news reports.

“All the intelligence in this drone has been completely decoded and extracted and we know each and every step it has taken,” said Brig. Gen. Amir Ali Hajizadeh, Commander of the Aerospace Division for the elite Islamic Revolutionary Guard, according to an English-language report by Iran’s semi-official Fars News Agency. …

The RQ-170 Sentinel drone, a classified unmanned surveillance craft produced by defense contracting giant Lockheed Martin, was on a CIA mission when it mysteriously crashed in Iranian territory last December, according to U.S. officials at the time.
