(KUNA) -- A bomb blasted outside a Fatah activist's home in Beit Lahiya early Sunday morning, Palestinian security sources said. Hamdi Srour's house suffered severe damage from the explosion, but no casualties were reported. The Palestinian police have started an investigation into the bombing. The Rafah crossing was also attacked by gunmen last night. The gunmen fired from the crossing's south side. A speaker from the President's Guard who are in command of the crossing, Wael Thahab, told Palestinian radio, "the forces at the crossing fired back and forced the attackers to flee." Thahab did not openly accuse any faction of the attack but hinted to a group he left unnamed. He added, certain factions continue floundering Palestinian resources. Thahab continued, the President's Guard will not hesitate to return any attack on Palestinian sites that in the future will be the cornerstone of a Palestinian state.
