Palestinian weapons dealers display arms in the West Bank city of Hebron September 20, 2007. Four months after Islamist Hamas routed secular Fatah in the Gaza Strip, fears that clashes between the Palestinian rivals could erupt in the West Bank and uncertainty ahead of a U.S.-led peace conference are fuelling a scramble for guns. Dealers at the gun market in Hebron say weapons sales have jumped by up to 70 percent since Hamas took control of Gaza, while buoyant demand and supply bottlenecks due to tighter security have inflated prices.
