I know I’m a little late with this notice, but NPR has a nice piece about Banksy and others taking on the illegal barrier Israel has erected in the West Bank.

Hassan Salama, an unemployed laborer, walks curiously along a garbage-strewn dirt road in north Bethlehem that hugs Israel’s massive barrier. He looks at a painting of an enormous insect toppling colossal dominos that resemble the wall itself — and he cracks a slight smile.

“I don’t understand what it means. But I like it!” he says.

Nearby, along a main road leading out of Bethlehem, the British guerilla graffiti artist who goes by the name “Banksy” has painted a picture of a little girl in a bright pink dress frisking an Israeli soldier. Farther down the road, the elusive artist depicts an Israeli soldier checking the ID of a donkey.

Unfortunately, someone has already started to paint over his works:

Though his intention was to shed light on the plight of Bethlehem residents, British graffiti artist Banksy has received a poor review of some of the artworks he has stencilled around the West Bank town.

Unknown individuals have painted over one of the murals the pop artist recently created, while another was partially covered over, according to local reports.
