Arabs in Judea, Samaria, and Gaza demonstrated today and yesterday in support of Osama bin-Laden and against the United States air strikes in Afghanistan. The PLO has asked Arabs not to show their support for Osama bin-Laden. But, thousands of Arabs in Palestinian Authority areas insisted on rallying in solidarity with the international terrorist. In Shechem today, one such rally was held and the PLO dispersed it. On Monday, PLO armed militia men used live ammunition to disperse a pro bin-laden rally in the southern coastal region. Three Arab university students were killed and 210 were injured. In subsequent street battles there, 72 Arab civilians were injured by Arafat\'s forces. Today the PLO has closed several colleges in an attempt to halt pro Osama bin-Laden demonstrations. PLO officials have turned to Israel requesting apparatus for controlling riots.
