Wedding guests in Jerusalem celebrate the wedding by dancing with guns and knives. One guests dances with a knife pierced through a picture of Ali Dawabsheh, an 18-month-old who died with his parents when their home in the village of Duma in the occupied Westbank was torched in July.

Israeli officials describe the attack as Jewish terrorism.

Israeli authorities have seized the video and are investigating it. Charges are imminent in the arson case, but some of the suspects’ lawyers say that the Shin Bet security agency tried to extract confessions with torture. PM Benjamin Netanyahu said the video showed the need to curb violent Jewish zealots.
