An Israeli groom was indicted Wednesday along with a dozen party guests for celebrating the death of a Palestinian toddler who was burned to death alongside his parents during an arson attack last year, according to reports. The 13 people were charged with inciting terrorism and violence, which carries a sentence of five years in prison.

Eighteen-month-old Ali Dawabsheh was killed in July 2015 when his family's home was firebombed in the West Bank village of Duma. Ali's father, Sa'ed, and mother, Reham, were severely burned trying to rescue the child and later died of extensive injuries. Ali's 4-year-old brother survived with burns on 60 percent of his body. Israeli authorities immediately rounded up a number of suspects, but were later released citing lack of evidence. Two Israelis, Amiram Ben-Uliel and an unnamed minor, were indicted in January in connection to the attack.

Amateur video footage surfaced last December sparking outrage. The rowdy guests are seen chanting and dancing, holding knives, guns and Molotov Cocktails as they deface photos of Ali Dawabsheh. The partygoers sang Biblical songs, replacing certain words to reference vengeance against Palestinians. Israeli media labeled it the "Blood Wedding" affair.

The footage was broadcast by an Israeli news station, which reported that the featured marrying couple were "very well known in the radical right." Both Palestinian and Israeli politicians condemned the footage that Israeli Prime Minister Benjamin Netanyahu described as “shocking images [that] show the true face of a group that constitutes a danger to Israeli society.”

Those arrested include five minors between the ages of 14 and 17. One defendant, Sinai Tor, was allegedly a wedding singer and sang songs of blowing up and burning down mosques, while another defendant, Daniel Moshe Piner, wore a shirt bearing the message "there are no Arabs, there are no attacks" and held a banner bearing the colors of the Kach movement, considered illegal in Israel.
