Why can't I upload videos on my iPhone 5 to Facebook?

I tried thru the app and nothing. I also tried thru Safari and nothing. There's not even an option when I tap the "Share" option. Is it capable of even doing this? I know I could with my Android >=/

I had an android also and I have the iphone 5 and I cant figure out how to do that either! It only gives you a message option, youtube option, and one other option. Thats definitely annoying!
