How to delete linked Facebook contacts from my iPhone contacts?

I just had a new IPhone activated and all of my Facebook friends are in my contacts and when I hit delete contact it says 'linked Facebook contact will not be deleted.' Is there any way I can delete them from my phones contacts?

Go on settings and scroll down where you see the Facebook app thingy and click it and sign out

Settings > Facebook
Make sure contacts is set to off

What if I only want to delete one person from my contact list?

How I can't find how you delete them
