A second potential oil slick has been identified near Iran’s Kharg Island, a critical export hub, according to maritime intelligence firm Windward AI. This discovery intensifies concerns about an environmental disaster, as a larger oil spill detected on May 8 continues its advance toward Saudi Arabian waters.
This new suspected slick emerges as United Nations officials issued warnings on Sunday about the potential for an environmental catastrophe in the region, amid the persistent crisis in the Strait of Hormuz.
“Today at 11 a.m. local time, another possible oil spill was detected,” Windward informed Fox News Digital. The firm estimates the affected area spans approximately 12 to 20 square kilometers.
While Tehran blames foreign vessels for the spill, maritime experts suggest the primary slick, which the U.N. University Institute for Water, Environment and Health estimates at tens of thousands of barrels and covering around 65 square kilometers, is more likely due to aging infrastructure, pipeline ruptures, or a “war mode” environment threatening the waterway since February.
Satellite imagery this week has shown a suspected oil slick covering dozens of square kilometers near Iran’s key oil hub at Kharg Island.
“It’s crucial to investigate the source of the slick and monitor developments closely,” advised Dr. Kaveh Madani, a U.N. official, in a conversation with Fox News Digital.
“If this slick gets bigger, we should be seriously worried about there being a leakage of aging infrastructure,” Madani said, adding the slick was “moving away toward the southwest of the island.”
“We just have to see how it moves and if it gets closer to the centers of population. If it does, desalination operations also must be halted. The risk is low right now,” he said.
Madani also noted the slick is near a zone with a heavy concentration of pipelines and energy infrastructure.
“Keeping these infrastructure systems healthy and operational has been very hard for the Iranians even in peacetime due to sanctions,” he said, warning that amid conflict, a “major accident is very likely.”
Water circulation in the Persian Gulf is slow, meaning pollution can persist for extended periods, he added.
“We saw similar instances during the Gulf wars and the Iran-Iraq War, with these things impacting coastal communities, the fishing industry, marine life and even the intake of desalination plants,” he said.

The larger spill, visible in satellite images as a gray-and-white slick, was first detected west of Kharg Island, Windward AI reported May 8, and has been steadily moving.
“It is believed to be crude rather than bunker fuel and unlikely to have come from a ship, possibly originating from pipeline issues or a failed ship-to-ship transfer,” the firm said.
The spill could pass through Qatar’s exclusive economic zone within about four days, with possible landfall near Al Mirfa in the United Arab Emirates in roughly 13 days, according to Windward.
The incident comes as Washington ramps up “Economic Fury,” tightening sanctions and increasing its naval presence near the Strait of Hormuz to curb Iran’s oil exports.
Since Iran closed the strait in late February following the outbreak of hostilities, tankers have bottlenecked across the region as the vital oil chokepoint remains largely shut.
“We also know that there are many tankers in the area, so there is a chance of an accidental spill,” Madani said.

“As long as the closure of the Strait of Hormuz is there and the region is in a war mode, the environment would not be a priority, but monitoring the behavior of tankers would not be trivial,” he said.
Meanwhile, Jafar Pourkabgani, a lawmaker representing Bushehr province, claimed the slick was caused by “oil residue and ballast water waste from European tankers” discharged into the sea.
“This claim is false and part of the enemy’s psychological operation,” he wrote on X, referring to allegations Iran released oil due to full storage tanks.
Iran’s Oil Terminals Company also denied reports of a leak near Kharg Island, according to Reuters.
The company’s chief executive said Sunday that inspections found no evidence of leaks from storage tanks, pipelines, loading facilities or nearby tankers.
