In a security camera video that was released from Huwara, you can see the Arab mob surrounding the Jewish man’s car, attacking his vehicle [upper left corner].
An Arab ambulance then pulls up and blocks the road in front of the driver [1:03].
At that point the driver hits the gas trying to get away, hitting a few of his attackers in the process. The driver is blocked from getting any further by the ambulance. [1:12]
The mob then attacks the car again and tries to pull the driver out.
An army jeep pulls up, and around that point, the driver opens fire.
