Image: Abu Mazen's new palace
From here (comments are mostly in Hebrew). According to the person who posted it, it's Abu Mazen's 'guest palace.'
By the way, there are many luxurious homes in Judea and Samaria. Back in the old days, before the existence of the 'Palestinian Authority' necessitated bypass roads in order to prevent Jews from being murdered, we used to play a game when we road through the 'Palestinian' suburbs in Jerusalem on the way to visiting Mrs. Carl's sister in Samaria. In the game, we tried to choose in which house we would most want to live (based on the house and not the neighborhood).
But if you're wondering where all that western aid money to the 'Palestinians' went, this ought to give you an idea.
