Israel and Iran intensified their deadly air strikes Monday on the fifth day after Israel launched its first attack to dismantle Iran's nuclear capability.

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.
