Live updates: Israel-Iran conflict and diplomatic efforts as Trump weighs US involvement

Israeli airstrikes on Saturday targeted Iran’s nuclear research complex in Isfahan, the country’s largest, the deputy provincial governor told the semi-official Fars news agency.

The deputy governor said there was no leakage of hazardous materials because of the attack, but residents were advised to avoid the area so rescue and crisis management personnel could do their jobs.

Several other areas of Isfahan province were also targeted, but no casualties have been reported, the deputy governor said.

Iranian air defenses intercepted the Israeli attacks, but some got through, according to the official’s account.

The “majority of explosions heard during the attacks were emanating from air defense systems’ engagements, and others were due to enemy attacks,” the Fars report quoted the official as saying, without naming them.

According to the semi-official MEHR news agency, Akbar Salehi, deputy for security and law enforcement at the Isfahan governor’s office, said Israel carried out attacks on several locations in the province, but the oil refinery was not hit.

Some context: Israel struck the Isfahan Nuclear Technology Center in the first days of the conflict, with an Israel Defense Forces official saying last Saturday the facility sustained significant damage. The International Atomic Energy Agency said four buildings at the site were critically damaged, but a spokesperson for the Atomic Energy Organization of Iran said damage was limited.
