Banksy, who rarely comments on his work and keeps his real identity a secret, has made trips to the West Bank for years and has previously, under cover of night, painted the barrier itself. On a recent trip, he painted a mural on the barrier, just steps from his current project, showing a girl being pulled aloft by balloons.
Last year, four street murals in Gaza were attributed to him, including one depicting a Greek goddess amid the rubble of a destroyed house.
