Mystery drones have reportedly been spotted over Diego Garcia, one of the most strategically important U.S.-UK military installations in the Indian Ocean. British officials have confirmed awareness of drone activity but have declined to reveal operational details, citing security concerns. U.S. officials have also remained tight-lipped. Unofficial reports have alleged drone sightings near a fuel depot and claims of a curfew, though these details have not been independently confirmed. The identity of the drone operators, the type of aircraft involved and their origin remain unknown. With Diego Garcia hosting a major airfield, naval facilities and strategic military infrastructure, the reports have triggered fresh questions over security at the sensitive base.
