The UN has denied it covered up allegations of child abuse by French troops in the Central African Republic, after it suspended a senior UN official for leaking an internal report detailing the abuse.

A UN spokesperson said the report was not supposed to be made public in order to protect the identity of victims and witnesses.

Rupert Colville, a spokesperson for UN High Commissioner for Human Rights Zeid Ra'ad al-Hussein, said publication of the internal report risked making those named "extremely vulnerable to reprisals", the AFP news agency said.

The curfew which has been in place in Baltimore over the last 5 nights, after protests caused by the death of a black man while in police custody, has been lifted.

Troops with the National Guard have begun withdrawing from the city.

On Sunday morning, Baltimore Mayor Stephanie Rawlings-Blake said she did not want to maintain it longer than necessary.

Around 300 Yezidi captives have been killed by Islamic State near Mosul, according to a statement from the Yazidi Progress Party.

Thousands of Yazidis were captured by IS militants last year, when they took over huge swathes of land in northern Iraq.

Thousands of people took to the streets, a day after the officers involved in the death of Freddie Gray were charged with homicide, with many exuberantly celebrating the move, while demanding justice to be served.

"We will gather in peace and we will march in peace and we will march until police brutality ends in the United States," Malik Shabazz, president of Black Lawyers for Justice which helped organise Saturday's march, told the crowd, according to Reuters.

Using social media hashtags #BlackLivesMatter and #BlackSpring, rallies were also planned on Saturday in more than 20 US cities including Dallas, New York and Los Angeles.

At the rally at City Hall, protesters held signs that said, "Running black is not a crime in Baltimore" and "Who's policing the Baltimore City police?", the Baltimore Sun reported.

Mark-Anthony Montgomery of the group Hearts with Promise said the protesters are fighting a "war on poverty" and a "war on injustice."

The Germen president, Joachim Gauck, defying his government’s rejection of the concept, expressed support for Greek demands for reparations for the Nazi occupation of Greece in World War Two.
