This April 9, 2012 photo provided by the Institute for Science and International Security, ISIS shows suspected cleanup activities at a building alleged to contain a high explosive chamber used for nuclear weapon related tests in the Parchin military complex in Iran. A nonproliferation think tank has published satellite images of an Iranian military site linked to suspected secret work on nuclear arms that it says show strong evidence of a cleanup. The commercial satellite photos obtained by the Institute for Science and International Security of Iran’s Parchin facility appear to show that two buildings there were demolished. ISIS says that, and other activities at the site such as digging up and moving earth strengthen U.N. suspicions of a clean-up. (AP Photo/ISIS, handout) less
