Today’s strike on Iran’s Natanz enrichment facility was carried out by the United States, the Kan public broadcaster reports, citing unspecified sources.
According to the report, the US used “bunker buster” bombs to target the site.
The US dropped more than a dozen GBU-57 Massive Ordnance Penetrator bombs on the Fordo and Natanz underground nuclear facilities in June 2025, during Israel’s 12-day war with Iran.
The Kan report follows earlier reporting from Iranian media alleging that Natanz was targeted in a joint US-Israel strike.
