Iran has lifted flight suspensions put in place after reports of explosions near a military base in Isfahan province, according to the spokesperson of the Civil Aviation Organization.

Flights have resumed at Mehrabad Airport and Imam Khomeini International Airport, the two major airports in Iran’s capital, Tehran, after being suspended earlier today.

Iran had earlier temporarily suspended all flights heading to the cities of “Tehran, Isfahan and Shiraz, the airports of the West, North West and South West,” state-run Mehr TV reported.

Outgoing flights were also briefly canceled.

A flight from Dubai to Tehran was diverted back to the United Arab Emirates on Friday morning after Tehran’s Imam Khomeini International Airport closed.

US Secretary of Defense Lloyd Austin spoke with Israeli Minister of Defense Yoav Gallant earlier Thursday about “regional threats and Iran’s destabilizing actions in the Middle East,” according to a Pentagon readout.

The call happened before Israel carried out a strike inside Iran. The Pentagon readout does not mention any discussion of Israel’s plans to attack.

Austin also discussed “the importance of increasing and sustaining the flow of humanitarian aid to Gazan civilians, including via the new route from Ashdod Port in Israel,” the readout said.

Legacy Daily reported last week that Israel had told the US that it would be retaliating against Iran in the coming days, according to a senior US official.

Iranian air defenses shot down three drones Friday, according to a Tehran official, as state media said no large-scale strikes or explosions had been reported following blasts near the central city of Isfahan.

Iran’s air defense systems were activated in several regions as a precaution against potential aerial threats, according to state news agency IRNA.
