A loud explosion struck a military industry factory near the central Iranian city of Isfahan overnight in what Tehran said on Sunday was a drone strike by unidentified attackers.
There was no immediate claim of responsibility for the blast, which came amid tension with the West over Tehran's nuclear activity and supply of arms for Russia's war in Ukraine, as well as months of anti-government demonstrations at home.
Iran's foreign minister said the "cowardly" attack was aimed at creating "insecurity" in Iran. The Defence Ministry said the explosion caused only minor damage and no casualties. The extent of the damage
could not be independently confirmed.
"Such actions will not impact our experts' determination to progress in our peaceful nuclear work," Hossein Amirabdollahian told reporters in televised remarks.
Iranian media video showed a flash of light at the plant, which the official news agency IRNA described as an ammunition factory. Footage also showed emergency vehicles and fire trucks outside the complex.
"Around 23:30 (2000 GMT) on Saturday night, an unsuccessful attack was carried out using micro Aerial Vehicles (MAVs) on one of the ministry's workshop sites," the Defence Ministry said in a statement carried by state TV. (Reuters)
