Four Palestinians were killed Sunday in fresh clashes between the rival Hamas and Fatah factions in two separate incidents in the Gaza Strip. Two Fatah activists, including Bahaa Abu Jarad, a senior militant in the movement, were gunned down by unknown assailants in Beit Lahiya, in the northern Gaza Strip, on Sunday morning, according to dpa. Hamas denied any connection to the deaths. Following the incident, dozens of Fatah activists took to the streets in the northern section of Gaza to protest the killings. In the afternoon two Palestinians, one from Hamas and one from Fatah, were killed in renewed clashes which left 11 others injured, including three in critical condition. Spokesmen from Hamas and Fatah traded accusations over responsibility for the clashes. -- SPA
