According to this story, the stage will be 1000 square meters (over 10,000 square feet) and is being built with some 1200 iron poles. 10 people have been working 18 hour days since Thursday to build this, which will include electric generators in case the power goes out.
Imagine how many houses Hamas could build if it wanted to. You know, for all those people that we hear are still homeless since the Gaza war.
I wonder if UNRWA will mention this the next time it blames Israel for not allowing enough building materials into Gaza.
