There were actually two attempts. The more spectacular one was the Arab with the light shirt lighting and hurling the firebomb towards an unseen target - possibly to start a forest fire. His own clothes ignite as he rushes back into the getaway car, seemingly unaware that he is on fire.
His red-jacketed friend was driving with a tire as his companion. He rolls out the tire and pours gasoline on it, and tries to light it up as well, but without success.
The entire operation is amateurish but the brave Palestinians are clearly afraid of getting caught.
I particularly like how the getaway driver really wants to peel out and return to the village they came from before the arsonists can run back in and close their doors, and almost leaves the tire guy behind, but has to wait for traffic to allow the U-turn.
