BEITA, Occupied West Bank--A holiday hike by Israeli teen-agers ended yesterday in a melee of shooting and stone-throwing in an Arab town in which a 14-year-old Israeli girl and two Palestinians were killed.

Hours after the clash, Jewish settlers raided the nearby Arab village of Hawwara, smashing car windshields, beating villagers and breaking into homes, said Jihad Howari, the Israeli-appointed head of the village council.

The girl's death was the first of an Israeli civilian in the violence that has swept the occupied West Bank and Gaza Strip since December 8. At least 140 Arabs have died, according to U.N. figures, and one Israeli soldier has been killed.

The youngsters, children of Jewish settlers on the occupied West Bank, were on a Passover outing and had stopped for a picnic lunch when the trouble began with stone-throwing. Members of the group said Arabs offering to help then led them to Beita.

Arabs wrestled two automatic rifles from the group's two Israeli guards but did not fire them, the army reported.

Arab witnesses said the Israelis started the trouble by killing a Palestininan.

Army spokesmen originally said the girl, Tirza Porat, and several other teen-agers were shot but reported later that she was killed by a rock.

Eleven of the 18 hikers, the 60-year-old man acting as guide and one of the two Israeli guards were injured and two Palestinians were wounded by gunfire, the army said.

Dozens of settlers waving an Israeli flag later held a nighttime vigil about a half a mile from Beita, and said they would build a new settlement in the area. Army officials said the settlers left after several hours at the urging of troops who surrounded the village.

Scores of angry settlers also demonstrated in front of Yitzhak Rabin's home and called on him to resign, Israel radio said.

Israelis have been especially sensitive to the possibility of attacks on children, and warnings followed yesterday's fatal confrontation.

Foriegn Minister Shimon Peres said on Israel radio: "Israel will cut off the murderers' hands and will not let the evil terror achieve its aim."

According to Israeli witnesses and the army, the hikers stopped for a picnic lunch in a dry riverbed just outside Beita, 10 miles southeast of Nablus. Shmuel Fuchs, 15, said they had just sat down when a group of Arabs started throwing rocks.

The Israelis left the area, but soon "we discovered we were being followed by dozens of Arabs," said Fuchs, whose right arm and chest were bandaged. He spoke from his bed in Jerusalem's Hadassah Hospital.

He said some of the Arabs, apparently wanting to help, offered to lead the teen-agers out of the area through Beita, a town of about 12,000 people.
