Palestinian officials said Monday they plan to begin mass demonstrations against Israel's occupation of the West Bank on September 20, the eve of a largely symbolic UN vote expected to recognize their independence.

Palestinian official Yasser Abed Rabbo said leaders hope to attract millions, and the protest will be the first of a prolonged effort. He said the campaign would be called "Palestine 194," since the Palestinians hope to become the 194th member of the United Nations.

"The appeal to the UN is a battle for all Palestinians, and in order to succeed, it needs millions to pour into streets," he said. Abed Rabbo said all Palestinian demonstrations would be nonviolent.

The Palestinians have decided to ask the UN to endorse their independence. They plan to ask the powerful Security Council, whose decisions are legally binding, for approval as a full member of the world body.

The U.S. opposes the Palestinian initiative and has signaled it will use its veto power in the council to defeat the measure.

Israeli security officials have repeatedly expressed concern that mass unrest could quickly turn violent.

Israel's military chief, Lt. Gen. Benny Gantz, warned a parliamentary committee this week that "there is potential for a confrontation in September." He said the military expects "many thousands of people to conduct a quiet and nonviolent protest" that would move toward Israeli settlements or Israel proper. "The military will not be able to place the settlements at risk in such cases," he was quoted as saying.

Israeli leaders have appealed to the Palestinians to drop their UN initiative. Abed Rabbo said Monday that Netanyahu scuttled a secret meeting last week meant to head off the looming diplomatic showdown.

He said Israeli President Shimon Peres called his Palestinian counterpart, Mahmoud Abbas, and asked to meet, promising to bring some creative ideas for defusing the crisis. Abed Rabbo said Abbas traveled to neighboring Jordan for the secret meeting last Thursday, but at the last minute, Peres called to cancel, saying that Netanyahu opposed his ideas.
