In this  image released by ISIS, satellite imagery of the Parchin site is seen from April 9, 2012, taken before the beginning of major alterations undergone by the site starting in late spring of 2012. The original security perimeter and driveways to the various buildings are clearly visible as are the two small buildings that were later demolished. International officials engaged in a two-pronged effort Wednesday Dec. 12 2012 to engage Iran over concerns the country may have worked on nuclear weapons, with a U.N. team seeking access to a site linked to such suspected activity and European Union negotiators looking to restart talks with Tehran meant to ease such fears.   Emailing a series of commercial satellite photographs to The Associated Press Wednesday, the Institute for Science and International Security said the images showed a steady pace of what appears to be the reconstruction phase of the site which between April and July 2012 had undergone considerable alterations.
