New satellite images analyzed by CNN and the Institute for Science and International Security indicate that Iran is rebuilding parts of its suspected nuclear facilities. The images show reconstruction efforts at the Parchin site, which was damaged earlier this year by joint US-Israeli airstrikes. The activity appears to have taken place in June and July, shortly after Iran signed a 14-point memorandum of understanding with the United States pledging not to develop nuclear weapons.

Analysts cited in the report say the reconstruction could violate the terms of the June agreement, which aimed to end hostilities and ensure safe navigation through the Strait of Hormuz. The memorandum also included commitments by Tehran to refrain from nuclear weapons development and to cooperate with the International Atomic Energy Agency on uranium down-blending. Despite the new findings, the report notes that Iran’s main nuclear sites at Isfahan, Fordow, and Natanz remain untouched.

The satellite data also show Iran repairing some of its missile storage bases, raising renewed concerns in Washington and among its allies about Tehran’s broader military capabilities.
