A DRONE strike that triggered a fire near the United Arab Emirates’ main nuclear power facility has sharply escalated tensions across the Gulf, intensifying fears that the prolonged US-Iran conflict could spiral into a broader regional confrontation threatening global energy supplies and maritime security.
Officials in the United Arab Emirates confirmed on Sunday that a drone penetrated air defences and struck an electrical generator outside the inner perimeter of the Barakah Nuclear Power Plant, causing a fire but no radioactive leak or casualties.
The incident came as neighbouring Saudi Arabia announced that it had intercepted three drones entering its airspace from Iraq, warning that any violation of its sovereignty would be met with “necessary operational measures”.
Reuters cited, on Monday, authorities in Abu Dhabi said investigations were underway to determine the origin of the strike, describing the attack as a dangerous act of escalation.
A diplomatic adviser to the UAE president said the country retained the full right to respond to such “terrorist attacks”, whether carried out directly by “the principal perpetrator” or through proxy groups.
The UAE defence ministry said two additional drones had been “successfully” neutralised after approaching from the western border, although officials provided no further details regarding their launch points or intended targets.
Despite the attack, the UAE’s Federal Authority for Nuclear Regulation confirmed the Barakah facility remained secure and operational, with no release of radioactive material.
The International Atomic Energy Agency said emergency diesel generators were supplying power to Unit 3 of the plant and urged “maximum military restraint” around nuclear facilities.
The latest strike underscores the fragility of the ceasefire that took effect in April following weeks of conflict triggered by US and Israeli military operations against Iran beginning on February 28.
Although large-scale hostilities have subsided, regional security tensions have remained high, with drones repeatedly launched from Iraqi territory toward Gulf states hosting American military installations.
Iran has increasingly targeted Gulf infrastructure since US President Donald Trump announced a naval initiative aimed at reopening the Strait of Hormuz, one of the world’s most critical oil and gas shipping corridors.
The operation was suspended after 48 hours, but disruptions to maritime traffic through the strait have already contributed to what analysts describe as the most severe oil supply crisis in modern history.
More than five weeks after the ceasefire began, diplomatic negotiations remain deadlocked, with Washington and Tehran continuing to demand major concessions from one another.
The United States has called for Iran to dismantle its nuclear programme and relinquish control over shipping access through the Strait of Hormuz, while Tehran has demanded compensation for war damage, an end to US restrictions on Iranian ports and a halt to regional military operations involving Israel and its allies.
Trump intensified pressure on Tehran in a social media post on Sunday, declaring: “For Iran, the Clock is Ticking, and they better get moving, FAST, or there won’t be anything left of them. TIME IS OF THE ESSENCE!”
According to reports, Trump is expected to convene senior national security advisers this week to discuss possible military options relating to Iran.
Iranian officials responded with fresh warnings of retaliation.
Senior armed forces spokesperson Abolfazl Shekarchi said that if American threats were implemented, the United States would “face new, aggressive, and surprise scenarios, and sink into a self-made quagmire”.
Meanwhile, Iranian foreign ministry spokesperson Esmaeil Baqaei accused Washington and Israel of attempting to shift blame for instability in global energy markets following what he described as their “unprovoked military aggression against Iran”.
The maritime crisis has intensified further after Washington announced new enforcement measures targeting Iranian shipping activity.
US authorities said 81 commercial vessels had been redirected and four ships disabled to ensure compliance with sanctions and maritime restrictions linked to the conflict.
At the same time, Iranian officials signalled preparations for tighter control over shipping movements through the Strait of Hormuz.
Ebrahim Azizi said Tehran had developed a new mechanism to regulate vessel traffic through designated routes that would be revealed soon.
The broader regional conflict has already inflicted a devastating human toll.
Thousands of Iranians have reportedly been killed in US and Israeli air strikes, while fighting between Israel and the Iran-backed Hezbollah has left thousands more dead in Lebanon despite a recently extended ceasefire agreement. - May 18, 2026
