BEIT EL, West Bank (AP) _ Gunmen opened fire on Jewish settlers at a West Bank bus stop on Monday, killing a U.S.-born seminary student and seriously wounding another student.

No one immediately claimed responsibility for the drive-by shooting near the Beit El settlement. Israeli security officials have warned that Islamic militants opposed to Mideast peacemaking might stage attacks ahead of Israel's May 29 elections in hopes of hurting Prime Minister Shimon Peres' campaign.

Firing from a silver Mitsubishi, two gunmen first shot at a bullet-proof bus carrying Jewish settlers, leaving the windshield dented by about a dozen bullets. They then drove about one mile away and fired on people waiting at the bus stop.

David Reuven Boim, 17, was shot in the head and died later at Hadassah hospital in Jerusalem. He and his family had moved to Jerusalem from New York City 11 years ago.

``This is not a country with security, this is not a country with peace,'' his mother, Joyce Boim, told Israel radio.

``If boys can't leave the yeshiva (seminary) ... I don't know what kind of peace this is,'' she told Associated Press Television.

Another seminary student, Yair Greenberg, was shot in the chest and lower back. Hospital officials said he was in serious condition.

Two women aboard the armored bus suffered minor injuries when the driver braked suddenly, said a spokesman for the Magen David Adom emergency medical services.

One of the women, Rivka David, 26, was nine months pregnant and later gave birth to a son, Israel's Army Radio reported.

After the attack, the gunmen sped away toward the Palestinian refugee camp of Jalazoun. Their car overturned outside Beit El and the assailants drove off in another vehicle.

Israeli Maj. Gen. Uzi Dayan said it was not known whether the second car had been forcibly stopped by the gunmen, or had been involved in their plan.

About 3,000 mourners attended funeral services for Boim, who was buried in Jerusalem around midnight Monday.

Sources close to the family said he still held American citizenship, but no confirmation was immediately available from U.S. officials.

Palestinian leader Yasser Arafat called Peres to offer his condolences and pledged to continue fighting the Islamic militant groups, Israel radio said.

Peres' chances in the elections would be hurt by renewed attacks by Islamic militants before the vote.

Peres, the architect of Mideast peacemaking, is being challenged by opposition leader Benjamin Netanyahu, who has said he would make fewer concessions to the Arabs. Peres has maintained a slight lead in the polls during the past few weeks.
