A Taiwan Army helicopter crashed in Chishan town, southern Kaohsiung City, killing all eight people on board, local media reported on Wednesday.
The Bell UH-1H helicopter, also known as the Iroquois or 'Huey', was reported to be carrying out a drill on Tuesday when is crashed into a radio tower.
The helicopter took off from a base in Gueiren Township in southern Taiwan Tuesday afternoon and lost contact later.
All the eight bodies have been found.
Initial investigations attributed the accident to heavy fog in local mountain areas and poor visibility.
