JERUSALEM (JTA) — A video teaching viewers how to stab a victim correctly has been circulated on YouTube and has been shared with Palestinian social media outlets.

The video, which began circulating on Saturday and was first reported by the Israeli news website NRG, shows two masked men wearing black-and-white checkered keffiyahs and black clothing demonstrating the different stab positions.

The video emphasizes to viewers that they must turn the knife after stabbing in order to maximize the damage. It also shows how to stab someone surreptitiously and walk away.

It ends with the statement “What are you waiting for? Rise up and stab.”

On Friday, two Israel Police officers were stabbed near the Lion’s Gate in Jerusalem’s Old City.
