An Iranian drone was shot down as it 'aggressively approached' an American aircraft carrier in the Arabian Sea on Tuesday, a US military spokesman has said. An F-35C stealth fighter jet, which took off from the USS Abraham Lincoln warship, shot down the drone 'in self-defence' to protect the aircraft carrier and its personnel, according to US Central Command spokesman Capt Tim Hawkins. The ship was approximately 500 miles from the Iranian coast when the drone approached with 'unclear intent'. No US service members were harmed, and no equipment was damaged. The incident comes amid a growing US military presence in the region and heightened tensions between Washington and Tehran.
