Israeli airstrikes on Saturday targeted Iran's nuclear research complex in Isfahan, the country's largest, the province's deputy governor told the semi-official Fars news agency.
Several other areas of Isfahan province were also targeted, but no casualties were reported, the deputy governor said.
Iranian air defenses intercepted the Israeli attacks, but some of them succeeded, according to the official's account.
"Most of the explosions heard during the attacks came from engagements of air defense systems, and the others were due to enemy attacks," Fars quoted the official as saying, without naming them.
The deputy governor said there was no leakage of hazardous materials due to the attack, but residents were advised to avoid the area so that rescue and crisis management personnel could carry out their work.
According to the semi-official MEHR news agency, Akbar Salehi, deputy for security and law enforcement in the Isfahan governor's office, said Israel carried out attacks on several locations in the province, but the oil refinery was not hit.
Israel struck the Isfahan Nuclear Technology Center in the early days of the conflict, with an Israel Defense Forces official saying last Saturday that the facility suffered significant damage.
The International Atomic Energy Agency said four buildings at the site were severely damaged, but a spokesman for the Atomic Energy Organization of Iran said damage was limited.
