A drone struck an electrical generator at the UAE’s Barakah nuclear plant on Sunday as U.S.-Iran ceasefire talks stalled, with Trump warning Tehran time was running out.

Summary:

• A drone penetrated UAE defences and struck an electrical generator outside the inner perimeter of the Barakah Nuclear Power Plant, with radiological safety levels unaffected and no injuries reported, according to the Abu Dhabi Media Office.
• The UAE defence ministry said two other drones were intercepted and that the attack originated from the “western border,” while a diplomatic adviser to the UAE president described the strike as a dangerous escalation, per official statements.
• The IAEA confirmed emergency diesel generators were powering one unit at Barakah and called for maximum military restraint near nuclear facilities, according to the agency.
• More than five weeks after a tenuous ceasefire took effect, U.S. and Iranian negotiating positions remain far apart, with Washington demanding Iran dismantle its nuclear programme and reopen the Strait of Hormuz, while Tehran is seeking war reparations and an end to the U.S. port blockade.
• Trump posted a warning to Iran on Truth Social that the “clock is ticking” and is expected to meet senior national security advisers on Tuesday to discuss military options.
• Israel and Lebanon agreed to a 45-day extension of their ceasefire, though clashes have continued.

A drone strike set fire to an electrical generator at the United Arab Emirates’ Barakah Nuclear Power Plant on Sunday, marking a significant escalation in the broadening conflict between the U.S.-Israeli coalition and Iran, as diplomatic efforts to end the war appeared to be losing momentum.

The UAE defence ministry said two other drones had been intercepted before they could reach the facility, and that the attack had been launched from the country’s western border. Officials did not identify a specific perpetrator, but a diplomatic adviser to the UAE president said the strike constituted a dangerous escalation regardless of whether it was carried out by a state actor or one of its proxy forces. The UAE said it reserved the full right to respond to what it called a terrorist attack.

The International Atomic Energy Agency said emergency diesel generators had been brought online to power one of the plant’s units following the strike, and called on all parties to exercise maximum military restraint in the vicinity of nuclear infrastructure. Radiological safety levels were not affected and there were no casualties.

The attack came as the broader conflict, which began with U.S. and Israeli strikes on Iran on February 28, remained unresolved. A fragile ceasefire has been in place for more than five weeks, but the conditions demanded by each side remain irreconcilable. The United States has called on Tehran to dismantle its nuclear programme and lift its stranglehold on the Strait of Hormuz, the single most important corridor for global oil and gas shipments. Iran, for its part, has demanded financial compensation for war damage, an end to the U.S. blockade of its ports, and a halt to fighting across all fronts, including in Lebanon.

Trump, whose increasingly sharp rhetoric has failed to shift Iran’s position, warned on Truth Social that Tehran must act fast or face the consequences, and is expected to convene top national security advisers on Tuesday to assess military options. He held talks with Chinese President Xi Jinping during the week without securing any Chinese commitment to help broker a resolution.

Iran’s armed forces rejected Trump’s warnings, with a senior spokesperson saying any resumed attack would draw new and aggressive responses and drag the U.S. into what he described as a self-made quagmire. Iran’s foreign ministry accused the U.S. and Israel of deliberately destabilising energy markets following what it called unprovoked military aggression.

The disruption to Strait of Hormuz shipping has produced the most severe oil supply crisis on record. The U.S. blockade of Iranian ports has seen 81 commercial vessels redirected and four disabled as of Sunday. Iran signalled it was close to unveiling a designated transit route through the strait, a move that could further complicate the U.S. naval mission. In Lebanon, Israel and Hezbollah agreed to a 45-day ceasefire extension on Friday, though sporadic clashes have continued.
