Data 'extracted from US drone'

Military experts are in the final stages of recovering data from a US spy plane captured by Iranian troops, it was reported yesterday.

Tehran has flaunted the capture of the RQ-170 Sentinel, a surveillance drone with stealth technology, as a victory for Iran and a defeat for the US.

Washington is pressing for the return of the aircraft, which Iran says it forced to land about 140 miles into its territory using "cyber warfare methods". US officials dispute this, saying the drone apparently malfunctioned.
