George Floyd's brother - an American who was killed by a white policeman - called on the United Nations to "help the black Americans", at a time when the American prosecution charged a policeman in the city of Atlanta with murder after last week he shot an African American and killed him.

In a video message sent by brother Philones Floyd, Wednesday, to the United Nations Human Rights Council, and broadcast during an urgent session of the council on police racism and brutality, he called for an official investigation into "racist crimes and police violence against blacks in America", as suggested by African countries.

"You at the United Nations are the protectors of your brothers and sisters in America, and you have the authority to help us obtain justice for my brother George Floyd," Floyd said.

"The lives of black people are not important in the United States ... the way you saw my brother being tortured and killed while being photographed is the way the black police are treated in America."

The murder of Floyd by policeman Derek Chauvin in the city of Minneapolis, Minnesota on May 25, angered American society, as a result of which massive demonstrations erupted throughout the United States.

African countries want the council to adopt a proposal this week to form a committee to investigate racism, police violence and human rights violations against Africans or people of African descent in the United States and other countries affected by this phenomenon.

Since the formation of the Human Rights Council in 2006, 31 investigation committees and fact-finding missions have been formed. So far, no commission has investigated any western country.

If this plan is adopted this week, the United States will be added to the list of countries subject to such an international investigation, which includes Congo, Myanmar and Venezuela.

Accusation of murder

On the other hand, on Wednesday, the American prosecution accused a policeman in the city of Atlanta of killing after last week a citizen of African descent was shot in a parking lot in front of a fast food restaurant, killing him, while a colleague who is facing lighter charges agreed to testify against him in the case.

Fulton County District Attorney Paul Howard said - at a press conference - that the dead Richard Brooks - a 27-year-old father of three - had "never received any indication that he was a threat" and had not shown hostile behavior towards the two white policemen during Friday's confrontation the past.

He added that 11 criminal charges were brought against the police officer, Jarrett Rolfe, who shot Brookes, and was fired from his work the following day after surveillance cameras revealed what happened in the incident, and that the charges included criminal murder, assault with a deadly weapon and perjury in the right-of-work.

He added that Rolf, 27, could face life imprisonment or death if convicted.

His colleague, Devin Brosnan, 26, was charged with aggravated assault and violating the right-of-work. Howard said that Brosnan - who was referred for administrative work after the incident - had provided investigators with information supporting the charges against Rolf, and that he would cooperate with the prosecution.

In the context, the Atlanta City Police Syndicate announced that a number of its members had gone on strike to protest charges against their colleague Rolf Brosnan, and would only respond to distress calls if they related to calls from their colleagues requiring support.

It is reported that in the accident of the murder of George Floyd, policeman Derek Chauvin was charged with second degree murder, and three other Minneapolis police were charged with aid and collusion.
