Sikrikim ( Heb. סיקריקים ) is the name of a group of ultra-orthodox Jews who are close to the Neturey carto organization and known for scandalous actions and confrontation with secular norms of behavior in Jerusalem's Mea Shearim . The name dates back to the history of the Sikarii (daggers), who practiced methods of individual terror in the struggle against the Roman colonizers in the 1st century AD. er
