Iran continued repairing a secretive military facility linked to its nuclear weapons research while a temporary nuclear agreement with the United States was still in effect, according to a new analysis of commercial satellite imagery.
The images show construction activity at Taleghan 2, an underground facility located inside Iran’s Parchin military complex. The site has long been associated with research and testing connected to Tehran’s suspected nuclear weapons program.
Satellite photographs taken June 22 and July 7 reveal crews working to repair damage caused by earlier Israeli strikes, according to CNN and experts at the Institute for Science and International Security.

The work began just days after Iran and the United States signed a June 17 memorandum of understanding intended to freeze certain nuclear activities.
Analysts said workers excavated around three large holes in the facility’s roof that appeared to have been created by penetrating munitions. Crews also poured concrete reinforcements and installed what appeared to be rebar, suggesting preparations for a permanent cap over the damaged sections.
Initial activity appeared focused on assessing the destruction and clearing rubble. Later images showed more extensive reconstruction and structural reinforcement.
Taleghan 2 was first damaged in an Israeli strike in October 2024. Iran subsequently rebuilt the facility before Israel targeted it twice more in March.
The latest repairs were underway while the June agreement with Washington remained officially active. President Donald Trump said Wednesday that the United States had terminated the deal as tensions with Tehran escalated.
The satellite findings raise new questions about Iran’s willingness to abide by temporary diplomatic agreements and the ability of foreign governments to verify its compliance.
Parchin has drawn international scrutiny for years because of its role in Iran’s military infrastructure and its suspected connection to nuclear weapons development. With international inspectors often denied access to sensitive Iranian facilities, independent researchers increasingly rely on commercial satellite imagery to monitor activity at the sites.
The latest images provide another indication that Iran continued work at a facility tied to its nuclear ambitions even while presenting itself as a participant in negotiations with the United States.
