DUBAI/WASHINGTON: Israeli missiles have hit a site in Iran, ABC News reported late on Thursday, citing a US official, while Iranian state media reported an explosion in the center of the country, days after Iran launched a retaliatory drone strike on Israel. Commercial flights began diverting their routes early Friday morning over western Iran without explanation as one semiofficial news agency in the Islamic Republic claimed there had been “explosions” heard over the city of Isfahan. Some Emirates and Flydubai flights that were flying over Iran early on Friday made sudden sharp turns away from the airspace, according to flight paths shown on tracking website Flightradar24. “Flights over Isfahan, Shiraz and Tehran cities have been suspended,” state media reported. Israel had said it would retaliate against Iran’s weekend attack, which involved hundreds of drones and missiles in retaliation for a suspected Israeli strike on its embassy compound in Syria. Most of the Iranian drones and missiles were downed before reaching Israeli territory. The semiofficial Fars news agency reported on the sound of explosions over Isfahan near its international airport. It offered no explanation for the blast. Several Iranian nuclear sites are located in Isfahan province, including Natanz, centerpiece of Iran’s uranium enrichment program. Isfahan, Isome 350 kilometers (215 miles) south of Iran’s capital, Tehran, is also home to a major air base for the Iranian military. Unconfirmed posts on social media were saying at least seven Iranian cities were hit by strikes. Iran’s government offered no immediate comment. The Israeli military did not immediately respond to a request for comment. The state-run IRNA news agency reported that Iran fired air defense batteries early Friday morning across several provinces after reports of explosions near the city of Isfahan. It did not elaborate on what caused the batteries to fire, though people across the area reported hearing the sounds. The semiofficial Fars and Tasnim news agencies reported the sound of blasts, without giving a cause. State television acknowledged “loud noise” in the area. Hossein Dalirian, a spokesman for Iran’s civilian space program, said on the X social media platform that several small “quadcopter” drones had been shot down. It wasn’t immediately clear where that happened or if it was part of the ongoing incident in Iran. Iran told the United Nations Security Council on Thursday that Israel “must be compelled to stop any further military adventurism against our interests” as the UN secretary-general warned that the Middle East was in a “moment of maximum peril.” Israel had said it was going to retaliate against Iran’s April 13 missile and drone attack. Analysts and observers have been raising concerns about the risks of the Israel-Gaza war spreading into the rest of the region. Oil prices and jumped on the reports of the Israeli strike. Brent crude futures rose 2 percent to $88.86 a barrel, the dollar gained broadly, gold rose 1 percent and S&P 500 futures dropped 1 percent. Israel’s assault on Gaza began after Palestinian Islamist group Hamas attacked Israel on Oct. 7, killing 1,200, according to Israeli tallies. Israel’s military offensive has killed over 33,000 Palestinians in Gaza, according to the local health ministry. Iran-backed groups have declared support for Palestinians, launching attacks from Lebanon, Yemen and Iraq.
