Qawasameh tribe, is a major clan primarily based in Hebron, with roughly 10,000 members. Although many of the Qawasmeh were originally pro-peace moderates and supporters of a two-state solution, they were radicalised. One tribe faction, numbering several hundred, dominates Hamas' branch in Hebron and is a radical opposition faction within Hamas, which frequently sabotages Hamas cease fires with bombings and attacks, provoking Israeli retaliation.
