"The U.N. nuclear watchdog's increased access in Iran to monitor a landmark agreement with world powers still falls short of what it says it needs to investigate suspicions that Tehran may have worked on designing an atomic bomb... The IAEA suspects that Iran has carried out explosives tests relevant for nuclear bomb development at the facility southeast of Tehran, possibly a decade ago. Iran denies this and has so far refused to open it up for the inspectors. The watchdog also wants to see other locations, interview officials and study relevant documents for its inquiry into what it calls the "possible military dimensions" to Iran's nuclear program... A Western diplomat who closely tracks Iran developments but is not from one of the six powers - known as P5+1 as they group the five permanent U.N. Security Council members plus Germany -said the Geneva agreement 'almost totally neglects' this issue. 'Do we take the P5+1's relative silence on PMD as sign that it will only get lip service now and that the past is the past?' the envoy said."
