Israel's military reportedly struck targets inside Iran in retaliation for an unprecedented air attack Tehran launched last weekend on its sworn enemy, but the limited scope of the operation and a muted Iranian response appeared to indicate an escalation of the conflict had been avoided.
Explosions were heard early on April 19 -- the 85th birthday of Supreme Leader Ayatollah Ali Khamenei -- near the central city of Isfahan, with reports unclear over the cause.
Several major U.S. media organizations, all citing U.S. government sources, said Israel launched a missile or drones to strike targets inside Iran.
Video posted on social media and broadcast around the world showed several large explosions that were reportedly near Isfahan.
Iranian state media quoted officials in Tehran as saying the explosions were caused by air defenses that shot down three drones in the area of Isfahan.
Hossein Deliriyan, the spokesman for Iran's National Center for Cyberspace, refuted the U.S. media reports, saying in a post on X, formerly Twitter, that "there has been no air attack from outside the borders on Isfahan or other parts of the country."
Speaking at a mosque on April 19, Iranian President Ebrahim Raisi didn’t mention the attack near Isfahan and with the Israeli retaliation limited in size and scope, experts said it appeared it was aimed at deescalating soaring tensions while still sending a clear message to Tehran.
Reuters quoted an unnamed Iranian official as saying that Tehran “has no plan to strike back immediately.”
Tehran launched more than 300 drones and missiles at Israel in the early morning hours of April 14, almost all of which were shot down by Israeli defense systems, along with intercepts by forces from the United States, France, Britain, and Jordan.
The attack by Tehran had been widely anticipated in Israel following a suspected Israeli air strike on the Iranian Embassy compound in Damascus, Syria, on April 1 that killed two brigadier generals.
Since then, diplomats and politicians around the world, fearing another major escalation of fighting in the Middle East, had urged restraint as they awaited Israel's response.

“I’m not going to speak to that [the suspected Israeli attack] except to say that the United States has not been involved in any offensive operations,” U.S. Secretary of State Antony Blinken said after a G7 ministerial meeting on the Italian island of Capri.
Iran's state news agency IRNA said air defenses fired from a large air base in Isfahan that is home to Iran's aging fleet of U.S.-made F-14 Tomcats acquired before the 1979 Islamic Revolution. Isfahan also houses facilities that are part of Iran's nuclear program, including its underground Natanz enrichment site.

One of Iran's top nuclear facilities, the installation at Natanz, is located in central Isfahan. Such sites have seen several sabotage attacks that Tehran has blamed on Israel.
"IAEA can confirm that there is no damage to Iran's nuclear sites," the UN nuclear watchdog said in a post on X, formerly Twitter.
"Director-General Rafael Grossi continues to call for extreme restraint from everybody and reiterates that nuclear facilities should never be a target in military conflicts. IAEA is monitoring the situation very closely."
Israeli strikes targeting a Syrian Army position in the country's south were also reported on April 19.
According to AFP, Rami Abdel Rahman, head of the British-based Syrian Observatory for Human Rights, said the strikes, which he attributed to Israel, "targeted a radar installation of the Syrian Army" between the provinces of Sweida and Daraa provinces.
Raisi had warned earlier this week that Tehran would deliver a "severe response" to any attack on its territory and the limited scope of the reported Israeli attack appeared to heed U.S. President Joe Biden's comment to Israeli Prime Minister Benjamin Netanyahu that Israel should show restraint with any response and instead "take the win" since the Iranian attack didn't have a great impact.
"It is absolutely necessary that the region stays stable and that all sides refrain from further action," European Commission chief Ursula von der Leyen said during a visit to Finland on April 19.
Inside Israel, some hawkish lawmakers appeared to acknowledge the strike while criticizing it.
"Feeble," wrote hard-right Security Minister Itamar Ben-Givir in a post on X, formerly Twitter.
Israel and Iran have been bitter enemies for decades but Iran's was the first direct attack by one on the other's soil instead of through proxy forces or by targeting each other's assets operating in third countries.
