Israeli Prime Minister Ariel Sharon said Sunday he favors lifting the ban preventing Yasser Arafat from traveling outside Ramallah so the Palestinian Authority president can attend the Arab League summit. Sharon's comments come a day after two back-to-back Palestinian terror attacks left at least 13 dead as Israelis had gathered outside at the close of the Jewish Sabbath. In response Israel helicopters and gunboats have totally destroyed the headquarters of Palestinian leader Yasser Arafat in Gaza. The operation came early on Sunday morning.
