The fragile ceasefire that had held between Iran and Israel since April 8 collapsed on Monday, plunging West Asia into one of its most turbulent periods of direct military confrontation on the 100th day of the ongoing conflict.
Within a span of less than 24 hours, the region witnessed missile barrages, retaliatory airstrikes, threats of further escalation, the involvement of regional proxies, and urgent diplomatic interventions by world powers seeking to prevent a broader regional war.
The day began with Iran launching a major missile barrage toward Israel, marking the first direct attack by Tehran since the cessation of hostilities on April 8. The strikes immediately triggered nationwide emergency alerts across Israel, with the Israel Defence Forces (IDF) activating air defence systems and warning citizens to remain vigilant.
In an official statement, the IDF said, “Sirens were sounded in several areas across the country following the identification of missiles launched from Iran toward Israel. The IDF identified missiles launched from Iran toward Israel. Defensive systems are operating to intercept the threat.”
Israeli military authorities initially reported the successful interception of two incoming missiles but cautioned that the threat was ongoing. Officials later warned that “additional barrages” had been launched toward Israeli territory, indicating that the attack was larger than first assessed.
The missile assault marked a decisive breakdown of the diplomatic restraint that had preserved the ceasefire for nearly two months and set the stage for rapid military escalation.
As tensions mounted, Iran sought to frame its actions as a response to Israeli military operations in Lebanon. The Commander of Khatam al-Anbiya accused Israel of repeatedly violating the ceasefire and committing war crimes.
“The aggressive Zionist regime, through its repeated violations of the ceasefire, has continuously escalated its acts of aggression against the oppressed people of Lebanon. These actions have been carried out with the green light and support of the criminal United States and amid the silence of international bodies. By employing prohibited weapons, including phosphorus munitions, the regime has committed war crimes,” the official statement said.
Iran further claimed that Israeli military operations in Beirut’s southern suburb of Dahiyeh had crossed previously established red lines.
“Despite previous warnings issued by the Islamic Republic of Iran, the child-killing Zionist regime has crossed all red lines and, by intensifying its attacks in southern Lebanon, has targeted the southern suburbs of Beirut (Dahiyeh),” the statement added.
Tehran’s warning culminated in an explicit threat of broader military action should Israeli operations continue.
“We had previously warned that if the crimes committed in Dahiyeh were expanded, we would strike targets within the occupied territories. The Zionist military must immediately cease its attacks against southern Lebanon and Dahiyeh. Should it expand its aggression in that area or respond to Iran’s action, it will face even more forceful and regret-inducing blows. In such a case, devastating operations will be launched against the regime and its supporters,” the statement said.
Israel responded within hours.
According to Iranian state media reports, powerful explosions rocked multiple Iranian cities as the Israeli Air Force launched a major strike campaign targeting strategic military infrastructure deep inside Iran.
Iran’s official news agency IRNA reported at least “two powerful explosions” in Tehran, while residents in Isfahan heard “at least three blasts.” The state broadcaster IRIB later reported “multiple explosions heard in Tehran, Tabriz, and Isfahan.”
The Islamic Revolutionary Guard Corps (IRGC) alleged that Israeli forces had employed “air-launched ballistic missiles” during the operation.
Confirming the attacks, the IDF announced that Israeli aircraft had struck military targets in western and central Iran.
The Israeli Air Force later expanded on the operation, saying, “Dozens of Air Force fighter jets, guided by Military Intelligence, completed a short time ago an extensive strike against the strategic defence systems of the Iranian terror regime.”
Additional Israeli military updates indicated that fighter aircraft had “attacked several targets at the petrochemical complex in Mahshahr,” a key energy and industrial hub located in southwestern Iran.
Iranian authorities sought to reassure the public following the strikes. The Tehran Fire Department stated that “urban areas were not struck” and noted that explosions recorded at 4:43 a.m. and 4:45 a.m. had not impacted residential districts.
Alongside the military confrontation, intense political manoeuvring unfolded in Washington.
In a telephone interview with the Financial Times, US President Donald Trump asserted that he remained firmly in control of efforts to manage the crisis and suggested that Israeli Prime Minister Benjamin Netanyahu had limited room for independent decision-making.
“He won’t have any choice. I call the shots. I call all the shots. He [Netanyahu] doesn’t call the shots,” Trump said.
The US President also insisted that the latest military escalation would not derail diplomatic efforts involving Tehran.
“It’s not going to have any impact on the deal,” Trump said.
At the same time, reports emerged that Trump had privately urged Netanyahu to avoid further military retaliation. According to Axios, the US President told the Israeli leader “not to retaliate” further following the Iranian missile attacks in an effort to preserve what remained of the ceasefire framework.
However, the conflict escalated further during the day.
Iran’s Islamic Revolutionary Guard Corps Aerospace Force announced the launch of a retaliatory military operation known as “Operation Nasr,” targeting two of Israel’s most significant military airbases.
The IRGC declared, “With trust in Almighty God, minutes ago the brave fighters of the IRGC Aerospace Force launched Operation Nasr, targeting key centres of the strategic air bases of Nevatim and Tel Nof.”
Iran said the operation was conducted in retaliation for Israeli strikes against Iranian radar installations and military infrastructure.
The regional dimensions of the conflict expanded simultaneously as Yemen’s Houthi movement joined the confrontation.
The Houthis launched a projectile toward Israel and announced a sweeping maritime blockade in the Red Sea.
“We declare a complete and total ban on Israeli maritime navigation in the Red Sea,” the group said in a statement posted on Telegram.
The declaration came amid reports of an Iranian blockade of the Strait of Hormuz, raising concerns among energy markets and global shipping operators about the potential disruption of critical trade routes through which a significant portion of the world’s oil supplies pass.
As military activity intensified, international leaders renewed calls for restraint and diplomacy.
UK Foreign Secretary Yvette Cooper warned that the latest escalation threatened both regional stability and global commerce.
In a post on X, she said, “The resumption of conflict between Iran and Israel is in no one’s interest. Both sides must…”
