Umm Al Quwain oil spill shuts beaches after tanker leak

The Umm Al Quwain oil spill forced the UAE to close every beach in the emirate on Friday, after a leaking tanker polluted the coast north of Dubai.

The Ministry of Climate Change and Environment said its monitoring systems detected marine pollution from an oil leak. It added that teams had begun containment, cordoning off and cleanup work.

The ministry did not name the vessel. However, the Umm Al Quwain oil spill came after a tanker came under attack earlier this month.

What the UAE says about the Umm Al Quwain spill

Residents in Sharjah, Ajman and Umm Al Quwain noticed odours. The ministry said they pose no health risk to people.

Authorities closed all beaches and coastal areas in Umm Al Quwain as a precaution, while survey work continues. Specialist teams are coordinating with other agencies to contain the pollution and limit damage to the marine environment.

On social media, many residents in the north of the country, including northern districts of Dubai, reported unusual oil-like smells in recent days.

The tanker and the Strait of Hormuz

On October 9, a maritime security agency reported that a projectile hit a vessel off the UAE coast and caused a fire, which crews later brought under control. A security firm identified the ship as the Panamanian-flagged oil tanker GEM NO.2.

Frequent attacks on ships have occurred near the Strait of Hormuz in recent weeks. Roughly a fifth of the world’s oil used to pass through the strait, before US-Israeli strikes on Iran launched the war in late February.

Both Tehran and Washington have put blockades in place. Iran has also repeatedly targeted cargo ships on the southern side of the waterway.

This week, Iran’s IRGC said it targets tankers that try to use what Tehran calls an unauthorised route near the Omani coast. Under international maritime law, Tehran has no recognised authority to restrict passage through the strait.

The UAE sits only 40 to 50 nautical miles from the narrowest point of the waterway. Another report noted that nobody has confirmed a link between the spill and Iranian attacks.

Pollution beyond the Umm Al Quwain oil spill

Researchers at the University of South Florida study the war’s effect from space. Brian Barnes said some of the major ships that came under attack left plumes that stretch for hundreds of kilometres.

His team compared March 2026 with the same month last year. They found twice the amount of surface oil they would expect without a major conflict. Satellites show only the surface, he noted, not how thick the oil is.

Earlier incidents also hit both shores of the strait. In August, Oman battled a spill from a grounded tanker. A few days later, Iran faced an oil release off Qeshm Island, near a breeding habitat of endangered hawksbill turtles.

Singapore’s maritime authority noted this month that vessels struck by projectiles can release fuel even when the main tanks stay intact. That harms wildlife and marine habitats.

Also, the Umm Al Quwain oil spill raises fresh questions about shipping safety. For now, the Umm Al Quwain oil spill leaves beaches shut, and clean-up teams continue to work along the coast.
