The video ends with the following message on a wall in Gaza: "If we wash our hands of the conflict between the powerful and the powerless we side with the powerful we don't remain neutral."
Banksy publicist Jo Brooks confirmed on Friday that he visited Gaza, getting there through a tunnel. Brooks would not say when the visit took place.Local residents were skeptical about this account since Egypt has stepped up its military campaign against the tunnels and destroyed most of them after last summer's war.
Jamal Abu Eitta, a 60-year-old, on whose home there is a graffiti depicting a watchtower, was equally unimpressed.
"We don't care about it. Gaza streets are full of posters, graffiti and drawings," he said.
It's not Banksy first foray into the Mideast conflict. He previously drew a painting of a girl pulled upward by balloons on Israel's West Bank separation barrier.
