ISRAELI police and Palestinian officials in the West Bank said they believe extremist Jewish settlers planted two bombs in a Palestinian schoolyard Tuesday. One device exploded, injuring five children.

　　Yehoshua Mor-Yosef, spokesman for the Jewish Settlers’ Council, said the bombing was an “immoral and illegal act.”

　　Israeli military officials said the explosion occurred near a water cooler in the courtyard of the Ziff junction secondary school south of Hebron.

　　The second bomb was found and safely detonated. The Israeli military controls the junction, a remote region populated mainly by Bedouins.

　　Israeli Foreign Minister Shimon Peres’ office, meanwhile, said the government had rejected a Palestinian cease-fire proposal during a meeting at the U.N. headquarters in New York.

　　The proposal by Palestinian Cabinet Minister Nabil Shaath called for an end to Palestinian attacks against Israeli civilians in a first phase and an end to all attacks in the second. Peres’ office said the plan was unacceptable because it would allow attacks on those not classified as civilians during its first phase. That was taken to mean Jewish settlers and soldiers in the West Bank and Gaza.

　　Shaath said the cease-fire also calls for an Israeli commitment to stop killing suspected Palestinian militants and destroying houses. “If Israel will do that, then this will pave a way for a comprehensive cease-fire, but unfortunately Mr. Peres said that he rejects it,” the Palestinian minister said.

　　In violence early yesterday, Israeli soldiers shot and killed a Palestinian gunman and wounded a second when they opened fire on troops and tried to run them down with a car, the army said. The incident happened in the West Bank village of Tamoun, near Jenin.
