JERUSALEM, JAN. 12 -- Israeli troops today prevented a high-ranking U.N. envoy from visiting a Palestinian refugee camp administered by the world body.

Marrack Goulding, the U.N. undersecretary general here on a fact-finding mission for the Security Council, was denied entry to Jabaliya camp in the troubled Gaza Strip when it was abruptly designated a "closed military area." That is Israel's term for locations not under formal curfew but placed off limits to the press or other outsiders in the current wave of Palestinian violence.

The incident reflected Israel's traditionally prickly relations with the United Nations and the coalition government's resentment of the recent Security Council resolution criticizing Israel's handling of the conflict and its decision to expel nine alleged ringleaders.

Also in Gaza, Israeli troops killed another Palestinian, one of a group allegedly trying to knife an Israeli soldier, as anti-Israeli demonstrations continued today, the second day of a general strike in the occupied West Bank and East Jerusalem.

At least 33 Palestinians have been killed by Israelis -- 32 of them by Army troops -- since the violence began Dec. 9. No Israeli has been killed in the disturbances in that period.

The incident with the U.N. official underlined Israel's determination to let nothing thwart its tough policy to suppress the outbreaks in the territories captured in the 1967 war. In recent days Israel has clamped on nearly continuous curfews, harassed food deliverers and carried out other forms of what the Israeli press has described as "collective punishment" to quell the disturbances.

"Goulding was disappointed since there was not much point to his visit to Gaza without getting into a camp," said William Lee of the U.N. Relief and Works Agency, which administers the refugee camps. A U.N. spokesman in Gaza said an UNRWA official entered the camp only minutes before Goulding's arrival and reported Jabaliya was peaceful and apparently not under curfew.

Goulding also tried to visit Mughazi, the only one of Gaza's eight refugee camps not under curfew or declared a closed military area.

But Goulding called off that visit after an emissary who entered the camp reported the atmosphere tense. U.N. sources said Goulding wanted to avoid provoking a confrontation between Israeli troops near the camp entrance and residents.

In an icy exchange in front of reporters later in Tel Aviv, Goulding told Defense Minister Yitzhak Rabin, "I made it clear throughout that the last thing we want to do was to provoke any confrontation."

Rabin, just back from a Gaza inspection tour of his own, said, "I understand in one camp we did not allow you in and in another camp the local people didn't allow you in."

Goulding retorted, "Your intelligence is better than that, minister."

Israeli leaders have long had difficult relations with the United Nations. Problems range from criticism of UNRWA to complaints about truce supervisory personnel and the U.N. peace-keeping force in Lebanon, which frequently has criticized Israel and its Lebanese allies for their actions in south Lebanon and for ignoring Security Council resolutions urging full withdrawal of Israeli forces.

In the continuing violence, Mohammed Youssef Yazuri was shot dead and three other Palestinians wounded when they attempted to knife a patrolling infantryman, according to the Army, which identified Yazuri as a member of the Moslem fundamentalist Islamic Jihad. Army officials said he had been released from prison a year ago after serving a three-year term for trying to seize an Israeli bus near Jerusalem and force it into a ravine.

Army troops also slightly wounded two Palestinians in an incident at Jabaliya, the Army said.

In the West Bank, four Palestinians were wounded in clashes with troops in Nablus, according to Palestinian sources, after a crowd tried to attack a police station.

Meanwhile, lawyers for four West Bank men singled out for deportation said their clients had abandoned attempts to appeal the orders because they were denied access to government evidence on grounds much of it was considered secret.
