The killing of detainee George Floyd by a police officer in Minneapolis shows the "true face" of America, Iran's supreme leader Ayatollah Ali Khamenei said Wednesday, according to AFP.

Speaking on the 31st anniversary of the death of his predecessor, Ayatollah Ruhollah Khomeini, Khamenei asserted that "The fact that a policeman has cold-bloodedly pressed his knee on the throat of a black man until he died and that other policemen watched on without doing anything is nothing knew."

"It is the true face of America, it's what it has always done all over the world -- in Afghanistan, Iraq, Syria and other countries, and before that in Vietnam.

"It is the normal course of action of the United States, it's the true face of their regime," Khamenei said.

"These are realities that have always been camouflaged or hidden, but they are not new."

Protests over Floyd's killing have raged across the United States for about a week.
