Iran has shot down an unmanned U.S. spy plane over its Fordu nuclear site by the Revolutionary Guards’ air defence units, a state-run website reported Wednesday, a day after it confirmed it was installing a new generation of advanced uranium enrichment centrifuges. The Fordu site was secretly built inside a mountain bunker near the holy city of Qom and was acknowledged by Iran after Western intelligence identified it in 2009. Iranian Foreign Ministry confirmed Iran was installing two more advanced models of the centrifuges used to refine uranium for large-scale testing at a research site. In January Iran announced it had shot down two unmanned western reconnaissance drone aircraft in the Gulf. Iran is at odds with major powers over its nuclear work. The United States and Israel, Iran's arch foes, have not ruled out military action if diplomacy fails to end the nuclear row. Pray: for Almighty God to bring Iran into his purposes and heritage amongst the nations. (Is.32:16 & Is.45:22) More: http://www.reuters.com/article/2011/07/20/us-iran-usa-plane-idUSTRE76J1WP20110720
