Three US Air Force personnel have reportedly been injured during a parachuting training exercise at a US Air Force base in Miami-Dade County, Florida, early Tuesday morning, the local NBC6 news channel reported.

The three injured victims were training for a HALO - High Altitude, Low Open - jump at Homestead Air Force Base, NBC6 reported, citing unnamed sources.

HALO jumps involve jumping from as high as 14,000 feet then waiting longer than usual to open the chute.

Emergency personnel arrived to the scene shortly after 4 a.m. local time, NBC6 reported, with all victims taken to hospital.

Their conditions are not known.
