Broad beans are the same thing as fava beans.

If you can get them fresh they may be green... it's been so long since I've seen them, I don't remember. In the USA it's rare to find them fresh (I suppose ethnic markets in big cities would have them regularly). I can only get the dried ones which are red. In either case they need to be peeled.

I've never been to the Middle East or Asia Minor, but the way I understand it is that chickpeas vs. favas is a regional variation rather than a substitution.
