TEHRAN, Aug. 24 (Xinhua) -- Iran's Islamic Revolution Guards Corps (IRGC) has downed an "Israeli spy drone" near Natanz uranium enrichment site in the central province of Isfahan, IRGC website reported on Sunday.
"After a spy drone of Israel was intercepted by IRGC's air defence system, it was targeted by a missile and downed," a statement by IRGC said.
"The downed drone was a stealth and radar-evading kind and aimed to penetrate Natanz nuclear air space," the statement said, adding that it was targeted by the IRGC's air defence system before entering the area.
The IRGC is ready to counter any threats posed to the country and "preserves the right for response and retaliation," it added.
Earlier on Saturday, Iran launched a uranium-conversion plant which will produce enriched uranium dioxide in Isfahan province within the framework of the agreement with the P5+1 group, namely Britain, China, France, Russia, the United States plus Germany.
Under an interim deal reached between Iran and the P5+1 that came into effect on Jan. 20, Iran would suspend some sensitive nuclear activities in exchange for limited sanction relief, and the two sides would negotiate over a comprehensive deal within six months.
After six months of negotiations, Iran and the six world powers agreed on July 19 to extend their talks until Nov. 24, as disagreements remained over Tehran's uranium enrichment capacity, its Arak heavy water reactor and the sanctions.
The two sides are expected to hold meetings in New York in September.
