TEHRAN, Iran (AP) — Iran has disrupted plots by foreign spies to recruit its nuclear experts and stopped sabotage attempts through faulty foreign equipment supplied for its facilities, the deputy head of the Islamic Republic's nuclear department told The Associated Press. In 2010, the so-called Stuxnet virus temporarily disrupted operation of thousands of centrifuges, key components in nuclear fuel production, at Iran's Natanz uranium enrichment facility. AP journalists weren't allowed to tour a nearby nuclear research reactor that went online with American help in 1967 — before Iran's 1979 Islamic Revolution strained ties between the two countries. Despite the negotiations, Zarean said its program remains a target for foreign spies, pointing at Iran's powerful Revolutionary Guard shooting down a purported Israeli drone last month near the uranium enrichment facility in Natanz, some 240 kilometers (150 miles) south of the capital, Tehran.
