Newly released satellite imagery has raised fresh concerns that Iran has begun reconstructing parts of its nuclear infrastructure damaged during US–Israeli strikes earlier this year, prompting questions over Tehran’s compliance with a June memorandum of understanding aimed at halting military nuclear‑related activity.
Analysis by the Institute for Science and International Security, reviewed by CNN, indicates that while several major nuclear sites remain largely unchanged, reconstruction work has begun at the underground Taleghan‑2 facility inside the Parchin Military Complex — a location long suspected by Western intelligence agencies of hosting nuclear weapons‑related research.
Images captured between June and early July 2026 show Iran has moved beyond debris removal and temporary patching and is now engaged in permanent rebuilding of the hardened underground complex. According to the institute, by June 12, Iran had already covered three bomb‑penetration holes created during US strikes, signalling rapid efforts to restore the site’s operational integrity.
Further satellite data from Vantor Technologies, dated June 22 and July 7, shows intensified activity: multiple trucks, heavy machinery and a large crane were observed at the site by June 18, suggesting large‑scale engineering work was underway. Debris was also seen being cleared from a nearby headquarters building destroyed during a separate bombing campaign between March 24 and April 1.
The findings have triggered renewed scrutiny of Iran’s intentions, especially as the Taleghan‑2 facility is believed to house test chambers and specialised equipment linked to weapons research. Analysts say the reconstruction raises doubts about whether Tehran is adhering to commitments made in the June MoU with the United States.
The developments come amid escalating regional tensions and ongoing US–Iran hostilities, with Washington monitoring the situation closely.
