The United Arab Emirates said on Friday that efforts were under way to contain oil leaking from a tanker vessel offshore, in a spill that prompted authorities to close beaches and warn fishermen to avoid the area, Reuters reported. The UAE Ministry of Climate Change and Environment said containment operations had been launched and an environmental assessment was being carried out.

All beaches and coastal areas around the city of Umm Al Quwain had been temporarily closed until technical teams completed their assessments and determined the necessary safety and marine protection measures, the ministry said, according to Reuters. The ministry also urged fishermen and other sea users to avoid affected areas and follow official instructions. Authorities in Sharjah temporarily closed Al Hamriyah Beach, on the UAE's northern coast near the border with Umm Al Quwain, as a precaution, the Sharjah Government Media Bureau said, Reuters reported. A Saturday summary of the response said Ras Al Khaimah and parts of Sharjah had also closed beaches until further notice as cleanup and survey work expanded along the northern coast.

UAE authorities have not named the tanker involved or said what caused the spill, and the environment ministry did not immediately respond to a request for comment, Reuters reported. Martin Kelly, chief executive of Orbital Risk Intelligence, told Reuters the spill was coming from a tanker called the Gem No.2, and analysts said satellite imagery from October 19 and 21 appeared to show a significant oil slick from the tanker. "The slick is considerably larger, covering approximately 160 km2, and looks to be coming from the ship," Leon Moreland, a researcher at the Conflict and Environment Observatory, told Reuters.

Reuters noted that since the start of the US-Israeli war with Iran, attacks on commercial vessels in Gulf shipping lanes have driven up security risks for maritime traffic and heightened fears over the conflict's environmental fallout. The northern UAE coast is home to fishing communities and to many Indian and Punjabi workers in the Gulf, for whom beach closures, fishing warnings and any wider shipping disruption have a direct livelihood angle. Officials have not released a spill volume, and no casualties from the spill itself were reported in the Reuters account.
