Israel used curfews, roadblocks and water cannons Friday to stop thousands of Arabs from attending Moslem Sabbath services at the Temple Mount, where police killed 19 Palestinians Monday.

In the occupied territories, troops shot and killed two Palestinians and wounded at least 10 in clashes with stone-throwing youths, Arab reports said.Also Friday, Prime Minister Yitzhak Shamir said Israel would reject any effort by the U.N. Security Council to send a team to investigate the Temple Mount deaths.

Shamir said a U.N. investigation would be an infringement on Israel's sovereignty over Jerusalem. Israel captured the Arab sector, which contains the Temple Mount, from Jordan in the 1967 Middle East war and later annexed it.

"In the recent past in the Middle East, there have been a number of incidents where people were killed," he said. "We did not see the Security Council being pressured to such grave discussions and with such broad outcomes."

The Arab League will hold an urgent meeting on the confrontation next Wednesday, sources in Tunisia said.

Defense Minister Moshe Arens said the United States was "trying to walk a fine line" in order not to jeopardize its international coalition against Iraq.

"But I think if they conclude that the way to keep this coalition is to blame Israel for an event whose roots lie in Moslem fanatacism, they will make a mistake," Arens said on Israel television.

Deputy Foreign Minister Bibi Natanyahu said the U.N. response to the events "lends rioters an international license to continue their rioting."

A Palestinian human rights group, Al Haq, issued a preliminary report on the killings, calling them a massacre and urging "international protection" for Palestinians.

The group said massive stone-throwing, which police say prompted their gunfire, did not begin until after tear gas was fired onto the Temple Mount. It also accused paramilitary border police units of opening fire without warning.
