Is 'worst of creatures' the correct interpretation in Quran?

http://quran.com/98/6

"Indeed, they who disbelieved among the People of the Scripture and the polytheists will be in the fire of Hell, abiding eternally therein. Those are the worst of creatures."

"... among the People ... are the worst of creatures"

Are conventional People called Creatures?
