Iran on Sunday issued a fierce condemnation of U.S. airstrikes targeting its nuclear facilities, labelling them a brazen breach of international law, the UN Charter, and the Nuclear Non-Proliferation Treaty (NPT).
The attacks, which hit key sites at Fordo, Natanz, and Esfahan, have escalated tensions in an already volatile West Asia, drawing sharp rebukes from Iranian leaders and global figures alike.
Iran’s Foreign Minister Abbas Araghchi minced no words in his denouncement. “The United States, a permanent UN Security Council member, has committed an egregious violation by attacking Iran’s peaceful nuclear installations. This morning’s events are unconscionable and will cast a long shadow. Every UN member state should be alarmed by this reckless, lawless act,” he posted on X.
Invoking Iran’s right to self-defence under the UN Charter, Araghchi warned that Tehran reserves “all options” to protect its sovereignty, interests, and citizens.
The U.S. strikes come amid a week of spiralling conflict between Iran and Israel, which saw both nations exchange blows on June 20. On Friday, European ministers met Iran’s top diplomat in Geneva, hoping to defuse the crisis, but the four-hour talks yielded no immediate progress. The U.S. action, announced by President Donald Trump on Sunday, has further inflamed the situation, derailing fragile diplomatic efforts.
Trump, in a televised address from the White House, hailed the strikes as a “spectacular military success,” claiming they had “completely obliterated” Iran’s nuclear enrichment facilities at Fordo, Natanz, and Esfahan. Just two days earlier, he had signalled a two-week window for diplomacy, making the attack a startling reversal. “Any retaliation by Iran will be met with force far greater than tonight,” Trump warned on social media, doubling down on his aggressive stance.
Iranian authorities, however, sought to reassure citizens near the targeted sites. The crisis management department in Qom, close to the Fordo facility buried deep in a mountainside, told state-run IRNA news agency, “There is no danger to the people of Qom or surrounding areas.” Iran’s Atomic Energy Organization, while asserting that the strikes violated international law, vowed that the country’s “national industry”—a veiled reference to its nuclear programme—would not be derailed. It remained tight-lipped on the extent of the damage.
The international community reacted with alarm. UN Secretary-General Antonio Guterres called the U.S. strikes a “dangerous escalation” in a region teetering on the brink, warning of “catastrophic consequences for civilians, the region, and the world.” Urging restraint, he stressed, “There is no military solution. Diplomacy is the only path to peace.”
Israeli Prime Minister Benjamin Netanyahu, however, praised Trump’s move as a “bold decision” that would “change history.” In a televised speech, he declared, “President Trump has acted to deny the world’s most dangerous regime the world’s most dangerous weapons.”
