The police plan to press charges against David Chaim, 25, of Haifa, for breaking a law banning unauthorized entry into the Palestinian Authority. Chaim, together with three Israeli-Arabs, entered the city of Tulkarm yesterday, and the four were kidnapped shortly afterwards by Fatah activists who realized they were Israeli. The three Arabs were released after about an hour, but Chaim was taken to the office of the city governor and was released only after the intervention of Yasser Arafat and Israeli-Arab MK Ahmed Tibi. Several Israelis have been murdered by Palestinians in the past few months after having PA-controlled areas mistakenly or purposely.
