A Palestinian man says he was conned into selling this Banksy mural on the door of his destroyed house

A Palestinian man says he was fooled into selling a valuable Banksy image painted on the door of his destroyed house in Gaza for just £100, according to Sky News.

Banksy's paintings can sell for hundreds of thousands of pounds. "I did not know that it was this valuable," the man says.

Representatives of the artist have asked that the painting be returned to the door's original owner, The Telegraph says.

The painting, titled "Bomb Damage," showed the Greek goddess Niobe holding her head in her hands. It was painted on the last remaining part of Rabie Dardouna's house in Gaza. The house had been destroyed, along with about 18,000 others, in Gaza's conflict with Israel last year.

Dardouna says he didn't know how much the mural was worth when he sold it. The painting was bought by a local artist, Belal Khaled, who says he didn't set out to con Dardouna:

"I bought the painting to protect its artistic value and preserve it from damage," he said. "Another reason is to display it in other places as well. I don't have any monetary interest in this."
