The best piece of advice anyone can offer you here, speaking as an Arab girl, is ignore everyone's advice, don't think too much about it and go and talk to her. Time spent speculating about someone you don't actually know is time wasted. Maybe she wants to be friends, maybe lovers, maybe something long term or maybe nothing, but which ever it is strike up a conversation and find out. Don't do anything your not comfortable with and try and not make her uncomfortable- just be respectful to her and yourself and that's all anyone can ask of you.
Chances are that she's more nervous of you than you her.
