The background to the incident is probably criminal.

United Hatzalah volunteers responded to the incident of violence that took place on Moshe Gastner/Tzvi Graetz St. in the German Colony in Jerusalem on Sunday afternoon and treated one person in critical condition and another person in moderate condition as a result of the violence.   

United Hatzalah volunteer EMT Yishai Solomon, who was one of the first responders at the scene said: "Together with other EMS personnel, I treated two people who were injured, one was in critical condition and another was in moderate condition. We performed CPR on the young man who was in critical condition at the scene of the incident. Additionally, we also treated a man in his 40s who was transported by a United Hatzalah ambulance to Shaare Zedek in moderate condition."
