DUBAI/JERUSALEM (Reuters)—Explosions echoed over an Iranian city on Friday in what sources described as an Israeli attack, but Tehran played down the incident and indicated it had no plans for retaliation—a response that appeared gauged towards averting region-wide war.
Iranian media and officials described a small number of explosions, which they said resulted from Iran's air defenses hitting three drones over the city of Isfahan. Notably, they referred to the incident as an attack by "infiltrators," rather than by Israel, obviating the need for retaliation.
An Iranian official told Reuters there were no plans to respond against Israel for the incident.
"The foreign source of the incident has not been confirmed. We have not received any external attack, and the discussion leans more towards infiltration than attack," the official said.
Israel said nothing about the incident. It had said for days it was planning to retaliate against Iran for Saturday's strikes, the first ever direct attack on Israel by Iran in decades of shadow war waged by proxies which has escalated throughout the Middle East through six months of battle in Gaza.
The two longstanding foes had been heading towards direct confrontation since a presumed Israeli airstrike on April 1 that destroyed a building in Iran's embassy compound in Damascus and killed several Iranian officers including a top general.
Iran's response, with a direct attack on Israel, was unprecedented but caused minor damage because Israel and its allies shot down hundreds of missiles and drones.
Allies including the United States had since been pressing hard to ensure any further retaliation would be calibrated not to provoke a spiral of hostilities. The British and German foreign ministers visited Jerusalem this week, and Western countries tightened sanctions on Iran.
In a sign of pressure within Israel's government for a stronger response, Itamar Ben Gvir, the national security minister, tweeted a single word after Friday's strikes: "Feeble!"
Within Iran, news reports on Friday's incident made no mention of Israel, and state television carried analysts and pundits who appeared dismissive about the scale.
An analyst told state TV that mini drones flown by "infiltrators from inside Iran" had been shot down by air defenses in Isfahan.
Shortly after midnight, "three drones were observed in the sky over Isfahan. The air defense system became active and destroyed these drones in the sky," Iranian state TV said.
Senior army commander Siavosh Mihandoust was quoted by state TV as saying air defense systems had targeted a "suspicious object."
Iranian President Ebrahim Raisi had warned Israel before Friday's strike that Tehran would deliver a "severe response" to any attack on its territory.
By morning, Iran had reopened airports and airspace that were shut during the strikes.
Still, there was alarm over security in Israel and elsewhere. The U.S. Embassy in Jerusalem restricted government employees from travel outside Jerusalem, greater Tel Aviv and Beersheba "out of an abundance of caution."
In a statement, the embassy warned U.S. citizens of a "continued need for caution and increased personal security awareness as security incidents often take place without warning."
Israel's assault on Gaza began after Hamas Islamists attacked Israel on Oct. 7, killing 1,200, according to Israeli tallies.
Iran-backed groups have declared support for Palestinians, carrying out attacks from Lebanon, Yemen and Iraq, raising fears the Gaza conflict could grow into a wider regional war.
