The Israeli army sent tanks into Nablus and began calling up reserves for a new military operation after Palestinians raided a West Bank settlement, killing a mother, three of her sons and a security official. Eight other people were wounded before Israeli troops stormed the house, killing one of the Palestinian gunmen. Meanwhile, Israeli forces fired on a market in the West Bank city of Jenin today, killing two children and a man and wounding dozens of other Palestinians. They mistakenly thought a curfew had been lifted. Also, Yasser Arafat appealed to Hamas, Islamic Jihad and the al-Aqsa Martyrs’ Brigade to halt attacks on Israeli civilians. The appeal comes after two suicide bombings over two days killed 26 Israelis and sent Israeli troops back into four West Bank towns. In Israel, there were growing divisions over Prime Minister Ariel Sharon’s decision to seize Palestinian areas and occupy them indefinitely. Defense Minister Binyamin Ben-Eliezer said he strongly opposed long-term reoccupation of Palestinian areas.
