Israel sealed off the West Bank Friday after suspected Palestinian militants killed two Israelis and critically wounded a third in a drive-by shooting after midnight on a road outside the capital.
The slaying was the first fatal attack on Jews in Israel since Prime Minister Benjamin Netanyahu took office, and it tested his vow to succeed where his predecessors failed in establishing a sense of security for ordinary Israelis.
After a stormy Cabinet meeting, Netanyahu issued a statement demanding that Yasser Arafat, the Palestinian leader, do more to "quash the terror of the terrorist organizations, without distinction."
But Arafat replied by denouncing the new blockade as "a breach" of agreements between Israel and the Palestinians. And one of his top advisers called the move "a barbaric act, a provocation and an act of revenge."
The Israeli army radio said the authorities believed that the gunmen belonged to the Popular Front for the Liberation of Palestine, a faction of the PLO that is opposed to peace with Israel.
The army imposed a complete closing of the West Bank, barring its 1-million Palestinian residents from entering Israel. Authorities said the closing would remain in effect indefinitely.
