Iran nuclear program: UN watchdog unable to access data since February

International Atomic Energy Agency says it can provide only an estimate of Iran's stockpile

The United Nations' atomic watchdog hasn't been able to access data important to monitoring Iran's nuclear program since late February when the Islamic Republic started restricting international inspections of its facilities, the agency has said.

The International Atomic Energy Agency (IAEA) reported on Monday in a confidential document distributed to member countries and seen by the Associated Press that it has not had access to the data from its online enrichment monitors and electronic seals, or had access to the measurement recordings registered by its installed measurement devices" since 23 February.
