The U.S. strike on Iran’s main nuclear site Fordow on Sunday destroyed critical infrastructure and rendered the enrichment facility inoperable, the Israeli prime minister’s office said, citing the country’s atomic agency.

Israel ratcheted up attacks on Iran while Tehran vowed to retaliate against US strikes on its nuclear facilities, fueling fears of a wider war in the Middle East and unnerving global markets.

Israel continued to trade missile strikes with Iran in the days after the U.S. targeted 3 Iranian nuclear sites.
