Nablus - The Israeli occupation army at dawn Monday swept into the West Bank city of Nablus and rounded up six Palestinians after storming and ransacking their family homes, witnesses reported. The sources said that the Israeli soldiers, garbed in plain clothes and accompanied by police dogs, held as many as 40 Palestinian civilians for a long while and even forced them to strip. The IOF fired at a Palestinian civilian car, causing damage to the vehicle but no casualties were reported amongst the passengers, according to the witnesses. Meanwhile, the IOF also on Monday pressed ahead with imposing tight siege on the West Bank city of Tulkarm, banning the Palestinian travelers from either accessing or getting out of the city, Palestinian sources said. The sources added that the troops erected military barriers at the city entrances at which they held the Palestinian civilian vehicles for many hours and accurately checked the passengers' IDS. The IOF on Sunday evening stormed Tulkarm city amidst intensified shooting as army vehicles were seen patrolling the city's streets. In the meantime, thousands of Palestinians in the northern Gaza Strip on Sunday evening laid to rest the 38-year-old Khader Rayan, one of the Aqsa Martyrs Brigades', Fatah armed wing, commanders, who succumbed to the wounds sustained in an Israeli missile raid last Thursday. Two of Rayan's comrades-in-arms were also killed in the raid. The mourners chanted anti-Israel slogans as AMB fighters vowed to respond to the Israeli assassination crime. Also Sunday evening, the IOF nabbed three Palestinian youths while strolling in the pastures located close to the western Ramallah town of Kfar Ne'ama, local sources reported. They said that the youth's kin were very much worried about their loved ones' destiny.
