A Palestinian man walks along the controversial Israeli barrier in the West Bank town of Bethlehem November 9, 2009. Palestinians are using the 20th anniversary of the toppling of the Berlin Wall to press their campaign against Israel's "wall" on territory they want for a state. Israel launched the barrier, which is mostly razor-wire fence interspersed with concrete barricades, in 2002 during a wave of Palestinian suicide bombings. While such attacks have dramatically dropped since, Israel has come under international censure for the barrier's de facto annexation of occupied West Bank land.
