In a one-minute video recorded on Thursday by a resident of the Aida refugee camp in the West Bank, an Israeli border officer speaking in Arabic broadcasts the message via a loudspeaker as an Israeli jeep drives through the street.
"People of Aida refugee camp, we are the occupation forces. You throw stones, and we will hit you with gas until you all die. The children, the youth, the old people – you will all die. We won't leave any of you alive," the officer says.
Earlier that day, Israeli border police arrested a 25-year-old Palestinian, who was ultimately released, Al Jazeera reported.
"We have arrested one of you. He is with us now. We took him from his home, and we will slaughter and kill him while you watch if you keep throwing stones," the officer continues.
"Go home or we will gas you until you die. Your families, your children, everyone – we will kill you."
Yazan Ikhlayel, 17, recorded the video after Israeli forces raided the camp during a protest against the occupation and fired tear gas, reportedly in response to Palestinian youths hurling stones at Israel's separation wall.
"The most important thing I want people to see when they watch this video is to realize what the Israeli 'democracy' really is," Ikhlayel told Middle East Eye.
"They have said it for us now, they are an occupation – they said 'we are the occupation army.' It is proof, this is an apartheid country, it is not democratic at all."
The border officer who made the threat has since been suspended, the Times of Israel reported.
The Badil Resource Centre for Palestinian Residency and Refugee Rights called the message a clear threat to kill Palestinians by way of extrajudicial executions, which would breach the Geneva Conventions.
"Such an announcement is remarkable in its stated contempt for human life, as well as raising a multitude of grave concerns as to the adherence of Israeli forces to central tenets of international law," Badil said in a statement.
