The IDF struck several targets at a petrochemical plant near Iran's southwestern city of Mahshahr, the military confirmed on Monday morning, following a second wave of Iranian missile attacks on Israel.
Parts of the site were damaged in the Israeli strike, and the area is being evacuated, Iran's Islamic Revolutionary Guard Corps-run Fars News Agency reported on Monday.
The strikes come after sources told The Jerusalem Post on Sunday that Israeli officials were still deciding when and how hard to hit Iran, noting that a significant Israeli response to Tehran's ceasefire breach was expected.
The IRGC claimed that the strikes were carried out using air-launched ballistic missiles, according to Iran's official state news agency IRNA.
Iran had threatened to attack Israel following an earlier IDF strike on Beirut, which itself was retaliation for continued Hezbollah ceasefire breaches.
Additionally, IRNA reported that all flights in Tehran's Mehrabad airport have been suspended until further notice.
Earlier on Monday, a United States official told Axios that he did not expect an imminent Israeli retaliation against Iran.
"I don't think anything is imminent in terms of an Israeli strike," he said.
Trump asked PM to hold off on strike
On Sunday, US President Donald Trump asked Prime Minister Benjamin Netanyahu to avoid striking Iran, N12 News reported.
"Israel has responded enough, no need for more," Trump additionally told KAN News.
Trump told Axios later on Sunday that the US is "very close to a final deal with Iran."
"I don't want it to blow up because of what is happening now," he said.
"If Netanyahu strikes them back, it's just gonna keep going like the last 47 years, or last 3,000 years," added Trump, noting that the Iranian attack on Israel "didn't hurt anybody."
Iran's Foreign Ministry Spokesperson Esmail Baghei said that the US holds direct responsibility for the recent ceasefire breaches, and that Israeli actions cannot be separated from US policies, according to Reuters. He further warned that the developments would only worsen the diplomatic process with the US.
IDF completes large-scale strike on strategic Iranian defense systems
The IDF completed a large-scale strike on strategic defense systems belonging to the Iranian terror regime
Earlier, dozens of Israel Air Force fighter jets, directed by the IDF Intelligence Directorate, completed a large-scale strike on strategic defense systems belonging to the Iranian terror regime.
Since the April 7 ceasefire following Israel having attacked the Islamic Republic in June 2025 and early 2026, the regime has rushed aggressively to rebuild its air defenses.
Recently, these defense systems were deployed in numerous areas across Iran as part of the regime's efforts to restore its detection and defense capabilities, which were degraded during Operation Roaring Lion.
The latest IDF attacks have further reduced these newly restored air defenses to enable the air force to attack more freely within Iran should the current round of fighting continue.
During Operation Roaring Lion, the IDF severely degraded the defense capabilities of the Iranian terror regime. These strikes further enhance the Israeli Air Force’s freedom of action in Iranian airspace.
