Tensions between the United States and Iran have surged to their highest level in months after a US air strike targeted the under-construction Darkhovin Nuclear Power Plant in southwestern Iran, marking a sharp escalation following the collapse of a one-month-old interim ceasefire last week.
In an official statement released after the attack, the Atomic Energy Organisation of Iran (AEOI) issued a fierce condemnation of the United States, framing the strike as an assault on a core symbol of Iranian national pride and the country’s decades-long push for technological self-reliance in the nuclear sector. “The terrorist and criminal US regime, whose very identity is rooted in bullying and open disregard for international law, has committed an aggressive, barbaric act that violates every norm of global governance,” the statement read. While the AEOI confirmed the strike targeted the nuclear construction site, it has not released any details on the scale of damage incurred, but reaffirmed that the attack constitutes a clear breach of international law.
Located in Khuzestan Province along the banks of the Karun River, the Darkhovin facility sits roughly 70 kilometers south of Ahvaz and 100 kilometers north of the Persian Gulf. Construction on the plant’s new reactor only began in 2022, and the project remains in its earliest phase of development. The International Atomic Energy Agency (IAEA), the United Nations’ nuclear oversight body, confirmed that no nuclear material was present at the site during its most recent inspection, meaning the attack does not pose any public radiological hazard. The agency announced it is currently investigating credible reports of the overnight strike. IAEA Director General Rafael Grossi repeated his longstanding call for global powers to exercise strict military restraint around all nuclear-related facilities, regardless of their operational status.
The strike on the nuclear site came as part of a broader wave of US air operations ordered directly by US President Donald Trump, which launched at 6 p.m. ET (10 p.m. GMT) Saturday, according to US Central Command (Centcom). In its official statement, Centcom said the strikes were ordered to achieve two core goals: to erode Iran’s capacity to disrupt commercial shipping in the strategically critical Strait of Hormuz, and to deliver immediate retaliation for a recent attack by the Islamic Revolutionary Guard Corps (IRGC) that targeted American service members stationed in Jordan. After completing the first wave of attacks, Centcom confirmed it had targeted multiple Iranian military assets, including coastal surveillance outposts and air defense systems along Iran’s southern coast.
Local Iranian media outlets have offered conflicting initial reports on casualties and non-nuclear damage. Iran’s state-aligned Mehr News Agency reported that one strike near the southern city of Sirik caused no reported casualties and no damage to major civilian infrastructure. Semi-official Tasnim News Agency also confirmed a second strike near Shadegan, a city located close to Iran’s border with Iraq.
The renewed full-scale hostilities follow the collapse of an interim ceasefire agreement that was signed roughly one month prior, ending a brief period of de-escalation and raising urgent fears across the global community that the two sides will return to open, all-out war. Earlier on Saturday, Iranian officials confirmed the country had formally withdrawn from a bilateral memorandum of understanding with the Trump administration, in response to the resumption of US bombardments across Iranian territory.
The current round of conflict traces back to February 28, when joint strikes by the United States and Israel were launched against targets across Iran, with the stated goal of disabling Iran’s nuclear and ballistic missile programs and weakening the network of regional proxies aligned with the Iranian government. That opening wave of strikes included an air attack that killed Ali Khamenei, Iran’s long-serving former supreme leader. The current supreme leader, Mojtaba Khamenei, who succeeded his father, has not appeared in public since the first day of the war, a point that has fueled widespread speculation about his status.
In a written statement carried by all major Iranian state media outlets Saturday evening, Mojtaba Khamenei issued a sharp rebuke of the Trump administration, arguing that the latest strikes prove any agreement signed by the US president is completely lacking in credibility and value. “Donald Trump’s signature is utterly worthless and devoid of credibility,” the statement read, warning that the United States will face “even heavier costs and further humiliation” in response to its aggression.
Beyond the immediate human and security risks, the escalating conflict has already triggered major ripple effects across the global economy: it has severely disrupted regional energy supplies, stoked new fears of sustained global inflation, and intensified the high-stakes competition for control over the Strait of Hormuz, the chokepoint through which roughly 20% of the world’s global oil supplies pass every day.
