Video footage has emerged of an Israeli Defence Forces (IDF) soldier cocking his assault rifle and pointing it at a Palestinian teenager's head in the West Bank town of Hebron.
The solider said he would "put a bullet in the head" of another Palestinian who was recording the incident.
The video - uploaded by the Palestinian activist organisation Youth Against Settlements - sees a heated exchanged between the soldier and a youth near Beit Hadassah in Hebron.
The youth pushes the soldier away from him. The soldier says: "It doesn't pay for you to do that again," before pushing the teen and aiming his rifle at him.
The soldier then runs up to another man who is recording the incident and threatens to kill him.
"Turn off the camera, turn off the camera, I'll put a bullet in your head, you son of a bitch," the officer says.
In response to the footage, the IDF Spokesman's Office said: "IDF forces that operate in Judea and Samaria and are responsible for maintaining security in the area must cope daily with a complex reality that demands professionalism, determination and good judgment.
"The behaviour of the soldier in the video was aberrant and does not meet the expectations of him. The matter will be investigated."
As a result of the video, the soldier - part of the Nahal Brigade infantry - is to be reassigned to another post in the West Bank.
