The Iranian Defense Ministry confirmed drone strikes at a military plant in Isfahan, calling the attacks "unsuccessful" with no casualties in a statement. The ministry didn't mention who was behind the attack. A fire broke out at an oil refinery near Tabriz at the same time. News agencies released videos of a flash of light at the Isfahan plant, thought to be a munitions factory. The Defense Ministry referred to the site as a "workshop" without further details. Isfahan houses a large air base and Iran's Nuclear Fuel Research and Production Center.
