Satellite imagery shows renewed activity at Iranian nuclear site struck by Israel in March

The Institute for Science and International Security released the satellite imagery on Friday, pointing to excavation work, heavy vehicle movements, and new construction at Minzadayi, a compound the institute describes as part of Iran's nuclear weapons program infrastructure. The site was among the Iranian targets struck by Israel in the opening stages of the war that began in February.

The institute's analysts cautioned that the activity may indicate Iran is moving to rebuild elements of its nuclear weapons development capability after the March strike. Tehran has not publicly responded to the assessment.

The finding lands in the middle of an escalating confrontation. The Houthis, Iran's allies in Yemen, struck Riyadh's international airport on Saturday, killing 12 and wounding 309, and President Trump said Washington may join Saudi strikes against the group. Earlier this month, Israel struck Gaza targets in response to what it calls Hamas rearming, and the Strait of Hormuz remains a flashpoint after Trump rejected an Iranian proposal to reopen the waterway in September.
