JERUSALEM -- Israel Defense Forces spokesman Effie Defrin said in a video briefing that Israeli air force fighter jets had completed an attack on the Isfahan nuclear facility in central Iran on Friday evening.

It added that the strike was carried out with precise guidance from the IDF Intelligence Directorate.

The IDF claimed that the site was undergoing a uranium re-enrichment process, the next stage after enriching uranium in the nuclear weapons production process.

The attack destroyed a uranium metal production facility, an infrastructure for converting enriched uranium, laboratories, and other infrastructure, it added.

Meanwhile, Israeli army chief Eyal Zamir said on Friday that it "continues with full force and at a high pace to meet the goals we have set," regarding the Israeli Air Force operation in Iran.

Speaking in a situation assessment with senior commanders, Zamir added that "there will be difficult moments... We are facing a dangerous and complex enemy, and we must maintain a very high level of readiness and discipline are required on the home front," according to a statement issued by the IDF.

Earlier on Friday, the IDF said in a statement that its fighter jets carried out a precision-guided airstrike on the Natanz nuclear facility overnight.

The facility, located in Isfahan province, is Iran's largest uranium enrichment site, which has been operating for years "to obtain nuclear weapons and contains the infrastructure required for military-grade enrichment," the statement claimed.
