Iran activated air defense systems across parts of Tehran early Thursday after explosions were heard in and around the capital, as exchanges of fire with U.S. forces continued across the region.
Military officials in Tehran province said an explosive sound reported near Pakdasht stemmed from an air defense operation in the nearby Parchin area rather than a direct strike, state-run IRNA agency reported.
The semi-official Tasnim News Agency reported that air defenses were activated in several districts across eastern and western Tehran after initial reports of explosions around Parchin and Pakdasht.
Explosions were also heard in Lorestan province in western Iran and Semnan in the north, while no casualties had been reported so far.
Meanwhile, Fars News Agency quoted a spokesperson in Semnan province as saying that parts of Semnan Airport were targeted by enemy airstrikes. Rescue teams were responding to the scene, while officials stressed that no residential areas in the province had come under attack.
Separately, Iranian officials reported that several locations in Kabudarahang County, northwest of Hamadan city in western Iran, came under an enemy attack early Thursday.
Hamadan Deputy Governor for Political, Security and Social Affairs Hamza Emrai said no casualties were reported, adding that Iran's armed forces were monitoring the situation and stood ready to respond to any further attacks.
The developments came hours after U.S. Central Command (CENTCOM) announced it had completed another round of strikes against Iran late Wednesday.
According to CENTCOM, U.S. forces struck Iranian command centers, air defense sites, missile and drone capabilities, and coastal surveillance facilities using precision munitions at multiple locations, including Bandar Abbas.
Earlier, the command said American forces had carried out a separate 90-minute operation targeting coastal defense and cruise missile sites on Greater Tunb Island.
CENTCOM said the strikes were intended to further reduce Iran's ability to threaten commercial shipping passing through the Strait of Hormuz.
Iran's military later announced that it had launched attacks on U.S. military assets in Kuwait, Bahrain and Jordan as part of its retaliatory campaign, Operation Lightning.
According to statements carried by Fars News Agency, Iranian forces targeted radar systems, Patriot air defense batteries and fuel storage facilities at Kuwait's Ali Al-Salem Air Base. In Bahrain, drones struck communications infrastructure, Super Hawk radar systems and Patriot installations at Sheikh Isa Air Base.
Iran also reported a separate drone attack on the U.S. Al-Azraq Air Base in Jordan, saying communications systems, a fixed radar installation and fuel depots were hit in retaliation for recent U.S. attacks, including a strike on the Bampur barracks in Iranshahr that Tehran said killed seven soldiers.
The latest exchanges erupted over a dispute about how to implement the Pakistan-brokered Islamabad Memorandum of Understanding, particularly its provisions governing commercial shipping through the Strait of Hormuz.
Iran has insisted that the agreement gives it the authority to manage vessel movements through the waterway, while the United States argues that it guarantees unrestricted international navigation, fueling renewed military clashes.
