Although Iran maintains that its nuclear program is for peaceful energy purposes, Israel has long seen it as a threat. Israeli strikes have hit three of Iran’s nuclear facilities — Natanz, Isfahan and Fordow. Little damage appears visible in satellite imagery of Fordow.

The two powers have been exchanging barrages since Israel attacked Iran and killed many of the country’s top military leaders and scientists.

The headquarters of the Islamic Republic of Iran Broadcasting in Tehran was hit by an Israeli airstrike during a live broadcast Monday, setting the building on fire and knocking the network off the air for a short time.
