Iran's Nuclear Development

International pressure is mounting on Iran to suspend its nuclear program. Here are the latest developments since Iran's nuclear program came to light in 2002.

May 20, 2009 - Iran successfully test-fires a medium-range solid-fuel missile, apparently capable of striking Israel and U.S. bases in the Persian Gulf region.

Dec. 17, 2007 -- Russia delivers a shipment of nuclear fuel to the Bushehr nuclear power plant in Iran, a step that officials in Moscow and Washington say removes any need for Tehran to pursue an uranium enrichment program.
Dec. 3, 2007 - A National Intelligence Estimate concludes Iran stopped work on a suspected nuclear weapons program in 2003 and probably could not produce enough highly enriched uranium for a single weapon before the middle of the next decade, even if it restarted the program now.
