Israeli prosecutors on Tuesday demanded a life sentence for a Jewish man found to be the ringleader of a group that beat and burned alive a Palestinian teenager in 2014.

State prosecutor Uri Korb demanded that Israeli settler Yosef Haim Ben-David be given life for the killing of Mohammed Abu Khdeir, as well as 20 years for his kidnapping and an additional 15 years for other crimes.

Ben-David had initially pleaded insanity but was ruled sane last month.
