Rangers have slammed fans who appeared to be displaying a flag with a Nazi symbol at Ibrox yesterday.

Images began circulating on social media showing the flag being hung from a railing in the stadium during Saturday's game against Aberdeen. 

It appears to depict a Totenkopf, a skull and crossbones that became associated with the Nazi Party during World War II.Glasgow Times:

The symbol was adorned on the uniforms of the 3rd SS Panzer, an elite division of the SS, which was given the nickname 'Death's Head Division'. 

The flag also reads: "Rangers active unit 936 The Firm."

Ibrox bosses have since spoken out and slammed the banner, and revealed that an investigation has been launched. 

A spokesperson for Rangers said: "Clearly, this flag is absolutely unacceptable and the club condemns the displaying of it within our stadium in the strongest possible terms.

"The club can confirm an investigation is now underway."
