Israeli troops on Tuesday arrested 30 Palestinians in various West Bank cities, according to a Palestinian source. The arrest campaign came after a night of intensive attacks carried out by Israeli extremist settlers against Palestinian citizens, especially in the southern part of Nablus city. The Palestinian Prisoners' Society said in a statement that Israeli soldiers stormed the cities of Jenin, Nablus, Qalqilya, Salfit,Ramallah, El-Beira, Bethlehem and Hebron and arrested 30 citizens, under the pretext they were wanted by Israeli authorities.
