Satellite pictures reportedly are showing increased activity at an Iranian site suspected of housing secret work on the country’s nuclear weapons program.
The disclosure was made Monday by The Associated Press, which cited officials from member countries of the United Nations nuclear watchdog organization, the International Atomic Energy Agency.
Iran is trying to hide its actions, the report said, by removing evidence of nuclear research and development.
The increased activity includes many vehicles coming and going, according to the AP, which is viewed as evidence that Iran is trying to sanitize the area.
Iran has said it is only producing nuclear power but has not allowed representatives of the IAEA in the country for the past three years.
Earlier this month, the IAEA issued a report saying there was “credible” evidence that Iran was working on a nuclear weapon.
