Satellite images appeared to show scores of trucks lined up at Iran’s Fordow nuclear facility just days before the US carried out its large-scale airstrikes — as speculation swirled that Tehran may have been able to move its uranium stockpiles before the attacks.

The images, released by US defense contractor Maxar Technologies, captured more than a dozen cargo-style trucks lined up outside the Fordow nuclear enrichment site’s tunnel entrance on Thursday and Friday.

The vehicles, which came and went over a 24-hour stretch, appeared to move unidentified contents roughly half a mile away, the Free Press reported, citing US officials.
