Artists add protest work to Bethlehem's wall

A little girl with pigtails in a pink dress pats down an Israeli soldier standing spread-eagle against the wall. Down the road, another soldier has stopped a donkey for questioning and is checking its ID.

Nearby, a large rat holding a slingshot appears ready to launch a few stones as he gazes up at Israel's towering concrete wall separating Bethlehem from Israel.

This is "Santa's Ghetto," an ongoing collaborative graffiti project that has evolved into the biggest artistic assault on Israel's separation barrier and the latest hope among Bethlehem's leaders to draw tourists back to this troubled town during the Christmas season.
