Israeli warplanes today bombed Palestinian guerrilla bases in southern Lebanon for the first time since the 1982 invasion of Lebanon, killing one person and wounding at least four during the 10-minute strike.

About two hours after the raids, a man with Jordanian Army papers entered the Israeli-occupied West Bank from Jordan and ambushed an Israeli Army patrol, killing two soldiers and wounding two before he was shot dead, the Israeli military command said, according to The Associated Press. Israeli officials said there was no indication that the attack had been done with Jordanian knowledge.

[ Early Thursday, an Israeli police intelligence officer handling Arab affairs was shot to death in a car in a machine-gun ambush at the busy Jaffa Gate of Jerusalem's walled Old City, Reuter reported. Two other Israeli passengers were wounded when the car came under automatic-weapons fire from another vehicle, police sources said. All three Israelis wore civilian clothes.]

The air raids came three days after a small bomb exploded at a Jerusalem pizzeria. It was Israel's first strike against Palestinian guerrillas since Israeli officials said they would retaliate for two Palestinian terror attacks that killed 20 persons last month at the Rome and Vienna airports.

The Israeli military command in Tel Aviv and Palestinian sources in Sidon said that the targets were three houses occupied by factions of the Palestine Liberation Organization opposed to Yasser Arafat's leadership.

One of the factions -- Fatah Uprising, led by Abu Musa -- had said it carried out the bombing Sunday of the Jerusalem pizzeria, in which nobody was injured.

Witnesses said four Israeli jets swept in low over the Mediterranean at dawn and dropped bombs on the houses, on the outskirts of the Ain Hilweh refugee camp, flattening one of them and heavily damaging the others.

Ain Hilweh, with 30,000 refugees, long has been a stronghold of guerrillas belonging to Yasser Arafat's mainstream Fatah wing of the PLO, but the camp was not hit.

Sidon residents said the raid caused panic in the camp as hundreds of refugees fled into the city, about 30 miles north of the Israeli security zone at the border.

Israeli jets made more than a dozen raids on Palestinian targets in Lebanon last year, but most of them were in the Syrian-controlled Bekaa Valley in eastern Lebanon. Today's raid appeared designed to avoid the Syrian surface-to-air missiles that were deployed in the Bekaa and just inside the Syrian border in November after Israeli jets shot down two Syrian MiG23s over Syria.

Israeli Prime Minister Shimon Peres, on a visit to West Germany, told reporters that today's raid was a justified action that struck at "a center of terrorism."

Israel has repeatedly said that it will strike at Palestinian guerrilla bases wherever and whenever it sees fit, but Israeli officials did not attribute today's strike to any specific guerrilla action.

The AP added from the West Bank:

The shootout between Israeli troops and the infiltrator from Jordan occurred near the Shadmot Mehola collective in the northeast corner of the West Bank.

The infiltrator crossed the river overnight near a Jordanian Army post, hid behind a boulder 600 yards from the Israeli-Jordanian cease-fire line and opened fire with an assault rifle as the foot patrol came down a steep road followed by a jeep with a mounted machine gun, Israeli military sources said.

The last infiltration reported from Jordan occurred in August 1981 in the same area, about a mile from the Jordan River.

Israeli military sources said they were not sure the military identification papers belonged to the attacker. Jordanian Information Minister Mohammed Khatib and Nabil Amer, PLO spokesman in Amman, said they had no information on the attack.

An Israeli Foreign Ministry official said Israel would ask the United States to discuss the infiltration with Jordanian authorities, but he doubted Jordan had advance knowledge of the attack
