Jay Z has taken out a full-page of advertisement in several newspapers across the US to tribute the death of George Floyd. 

Floyd, a 48 year-old black man, died in Minneapolis on May 25 after a white police officer knelt on his neck for nearly nine minutes, and as a result has been charged with third-degree murder.  

The US rapper and his Roc Nation company replaced advertisements in newspapers with a speech Dr Martin Luther King gave in Selma.

The spread also showed the signatures of various attorneys, fellow activists, and victims of police brutality.

On Tuesday, the ad ran in the New York Times, the Chicago Tribune, the Philadelphia Enquirer and more. 

One section of the speech read: "A man dies when he refuses to stand up for that which is right. A man dies when he refuses to stand up for justice. A man dies when he refuses to take a stand for that which is true.

“So we’re going to stand up amid horses. We’re going to stand up right here, amid the billy-clubs. We’re going to stand up right here amid police dogs, if they have them. We’re going to stand up amid tear gas!” 

It was signed by the parents of Botham Jean, DJ Henry and Antwon Rose II, all black men who were killed by the police. 

Other signatures included George Floyd’s lawyers and organisations such as Until Freedom and The Innocence Project.
