Will someone explain, as briefly as possible, what the deal is in the Middle East?

What religions are involved? Why are they fighting? What is the Gaza strip? Who is in the Gaza strip? Who are the Hamas?

On the Tide Pool someone (I think it was Hear Kat) posted a video, an animation, to explain it, but I can’t play it. :(

I know I could Google it all, but I’d rather hear it from you guys.
