The Israeli occupation forces launched today a campaign of raids, searches and arrests in many provinces of the West Bank, on the pretext of searching for the wanted Palestinians. The local Palestinian sources said that the occupation forces stormed and raided various parts of the Arab governorates of the West Bank and arrested 13 Palestinians. The Israeli occupation army also arrested yesterday in Ramallah, Qalqilyah, Nablus and Bethlehem, 16 Palestinians after a search of homes and their contents and then tampered with them before the army's withdrawal.
