In this Nov. 6, 2009 file photo Palestinian demonstrators throw stones at Israeli soldiers, behind barbed wire littered with spent tear gas canisters, during a protest against the barrier in the West Bank village of Bilin, near Ramallah. Israel arrested the leader of the most persistent Palestinian protests against Israel's West Bank separation barrier on Thursday, Dec. 10, 2009. Bilin is a symbol of opposition to the barrier, portrayed by Palestinians as a land grab. The barrier separates Bilin from 60 percent of its land.
