We found new activity at the Esfahan tunnel entrances that occurred during the last few days. The northernmost tunnel entrance shows vehicles present and that access to the tunnel portal, which was previously blocked by backfilled dirt, has been gained within the last week. The middle tunnel entrance shows activity in mid-July, including heavy machinery present, but no significant progress appears to have been made towards establishing tunnel portal access as of the end of July. The roadblocks on the road to the southernmost tunnel entrance remain; no activity is visible there.
Also at the main Esfahan site, minimal activity is visible around the destroyed buildings at the aboveground sites. Some roads have been cleared of debris but there is minimal vehicle presence. Several of the roads around the facilities remain uncleared from debris, with roadblocks installed.
At Fordow, the latest imagery of Fordow shows a new road being constructed towards the top of the lower hills on the east side of the Fordow site, away from the mountain containing the enrichment plant, but still within the outer security perimeters.
The earthworks in the area of the two ventilation shafts appear to have ceased. There is also no observable activity at the primary tunnel entrances leading into the enrichment facility.
We will continue to monitor the situation and provide updates as available.
