Large fire at Oklahoma gas plant forces major evacuations

A large fire Saturday afternoon engulfed a natural gas plant in the small northern Oklahoma town of Medford. Video posted to social media showed heavy flames and smoke billowing hundreds of feet into the air.

The fire occurred at a "natural gas liquids fractionation facility" operated by ONEOK, a company spokesperson confirmed in a statement to CBS News.

ONEOK said it was "unaware of any injuries."
