Palestine Press Agency has another article on Hamas corruption.
According to the article, Hamas has been seizing land that is already privately owned, and then sells it - either back to the original owner at an exorbitant price, or to a Hamas member at a fraction of that same price.
Two weeks ago, Hamas announced the sale of public lands, and the PA replied that Hamas has no right to sell that land, warning people against buying land that the PA claims for itself.
