Lehava is a prominent Israeli far-Right organisation whose name translates as "Prevention of Assimilation in the Holy Land". Pro-segregation, it is known for a violent campaign against relationships between Jews and non-Jews and shot to international attention for an arson attack last year on a Jewish Arab school. Mr Gopstein, a religious settler, has also been questioned by police after making comments appearing to justify burning down Christian churches, following an arson attack on the Church of the Multiplication of Loaves and Fishes in Galilee in June.
