Nokia Lumia 520's screen refresh rate is 30hz?

Is Nokia Lumia 520's screen refresh rate 30hz or 60hz?

I'm mainly asking this question because I wanna know if I'll be able to enjoy YouTube's new 60fps videos or not.

considering the Lumia 920's PureMotion branded display had a selling point of smooth 60 fps or something like that, I would think no. Although I dont know if the display sits at exactly 30 though.
