Grassroots Palestinian support for Bin Laden continues to cause problems for the Palestinian Authority, and in fact PA police have reacted so forcefully that six Palestinians Arabs have been killed. Thousands of Palestinian students and others demonstrated against the American offensive in Afghanistan over the past two days, and the PLO has closed several colleges in Judea and Samaria in an attempt to halt the rallies. PLO officials have turned to Israel requesting riot-control equipment, but Prime Minister Sharon has turned them down.
