Iran and Israel appeared to be easing off actions and rhetoric that could lead to a wider Middle East conflict after a series of apparent retaliatory attacks, the latest of which featured a suspected Israeli strike on sites near the central Iranian city of Isfahan.
Tehran on April 20 downplayed the scope and impact of the reported Israeli attack that appeared to be in retaliation for an unprecedented air attack the Islamic republic launched last weekend on its sworn enemy.
Explosions rang out 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, while several major U.S. media organizations quoted U.S. government sources as saying Israel had launched an attack on targets inside Iran.
Iranian state media quoted officials in Tehran as saying the explosions were caused by air-defense systems that shot down three drones.
Israel has not commented on the report.

Reuters, citing three sources familiar with the matter, reported that Israeli Prime Minister Benjamin Netanyahu's war cabinet initially approved plans for a strike inside Iranian territory to respond forcefully to Tehran's April 14 missile and drone strike but backed off at the last minute.
The sources said three voting members of the war cabinet ruled out the most dramatic strike: an attack on Iran's nuclear facilities and other sites that would likely have provoked a wider conflict.
The Reuters report said Netanyahu faced cabinet divisions and strong warnings from allies, including Washington, not to escalate matters, leading to two postponements of the limited strikes that eventually were launched.
Sanam Vakil, director of the Middle East and North Africa program at the Chatham House in Britain, was quoted by AFP as saying the reported Israeli strike had been "calibrated to avoid damage and further Iranian aggression."

He warned that if Israel strikes again, Iran will respond immediately and "at maximum level."
"If Israel retaliates, then we will respond. But if not, then we're done," Amir-Abdollahian told NBC News in Persian late on April 19.
He added that there are no signs to prove that this action was the work of Israel.
"They [the drones] took off from inside Iran, they flew like a few hundred meters and then they were downed, they were struck by our air defense. It's not even proven that there is a connection between these and Israel," Amir-Abdollahian said through an Iranian official interpreter.
"Two or three, they're more like toys that our children play with, not drones. It was not worth telling us," he said when asked whether any other country had warned Tehran in advance about an expected attack.

Speaking at a mosque on April 19, 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.
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.

However, according to Italian Foreign Minister Antonio Tajani, Washington informed the Group of Seven nations (G7) that it had received word from Israel on the strikes at the "last minute," but “there was no sharing of the attack by the U.S. It was a mere information.”
“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-defense systems 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.
The International Atomic Energy Agency (IAEA) said it had seen no damage to Iran's nuclear sites. Earlier this week, the sites were rumored to be a possible target if Israel launched a strike inside Iran.
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."
Israel and Iran have been bitter enemies for decades, but this 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.
