Report: US Navy SEALs Conducted Secret Strait Mine-Clearing Mission
US Navy SEAL divers reportedly spent four months looking for mines in the Strait of Hormuz.
Mines are underwater explosives that can damage or sink ships.
The divers worked with robots, unmanned boats, and special sonar equipment.
They often operated at night during fighting involving the United States and Iran.
The goal was to make the waterway safer for commercial ships.
Iran said it had placed mines in international and Omani waters.
A maritime organization estimated that about 80 mines were in important shipping routes.
President Donald Trump said all mines in international waters had been removed or destroyed.
However, the White House and the Department of Defense have not publicly discussed the reported covert mission.
US special forces reportedly spent four months clearing suspected mines from the Strait of Hormuz.
The Financial Times reported that Navy SEAL divers used unmanned vessels, robots, and underwater equipment, often at night.
Iran has claimed it placed mines in international and Omani waters after the war began.
The International Maritime Organization estimated that about 80 mines had been deployed along important shipping routes in June.
