The spark of demonstrations taking place in some American cities, protesting the killing of a black citizen by a white policeman, moved to Washington, DC, and other cities, at a time when National Guard and police units withdrew from downtown Minneapolis despite the entry into force of the curfew.

Hundreds of demonstrators gathered on U Street, one of Washington's most vital streets, to declare their rejection and condemnation of the incident.

The protesters chanted slogans such as "justice, otherwise there will be no stability." They also raised banners with slogans condemning the incident, and calling for justice such as "justice for Floyd", "urgent justice", "black lives are important", and "stop The police killed the blacks. "

After that, the protesters marched towards the White House amid tight security, as large numbers of police personnel were deployed around the area.

Soon clashes took place between police and demonstrators, some of whom burned American flags, and security personnel tried to prevent them from reaching the White House.

In New York, thousands of protesters gathered at the Barclays Center, and police arrested dozens of them in a massive demonstration in the Brooklyn area, while a highway in Denver was closed.

In Louisville, Kentucky, clashes took place while a number of residents were calling for justice for Briona Taylor, a black woman killed by police in her apartment last March.

Protesters attacked the headquarters of the "CNN" news in the American city of Atlanta on Friday evening. The network broadcast live footage from its headquarters, showing protesters outside, throwing objects at police at the entrance to the network.

A protester tried to break windows damaged at the entrance with his skateboard. The police presence in the area has been strengthened.

In Detroit, hundreds joined a "march against police brutality" outside the city's public safety headquarters and chanted "No justice, no peace."

Curfew

In Minneapolis, Minnesota, which witnessed the killing of an African-American citizen George Floyd while in police custody, hundreds of protesters violated a curfew and gathered in the streets around a police station that had been set on fire.

Angry demonstrators took to the streets of Minneapolis for the third night in a row, despite the curfew announced by the city's mayor, Jacob Fry, from 8:00 pm local time to the end of the weekend next Monday morning.

American media reported that the National Guard and police units withdrew from downtown Minneapolis and had no effect there, despite the previously announced curfew being implemented.

These demonstrations come after the announcement of the arrest of police officer Derek Chauvin and charges of manslaughter.

The video incident - which witnessed a widespread spread on the Internet - caused clashes and violence in the city of Minneapolis, which led to the deployment of National Guard forces to help the local police to contain the clashes, violence and fires.

Demonstrators set fire to the police building in the city on Friday, while the security authorities there are trying not to friction with the demonstrators, according to the local network, "CNN."

Voices rose across the country for justice, demanding the Floyd family accuse the police involved.

The video clip, policeman Derek Chauvin, shows his leg above Floyd's neck, knocked to the ground saying to him: "I cannot breathe ... I cannot breathe ... do not kill me."

After being chained, it was noticed that the forty-year-old man lost consciousness, so the ambulance was called and taken to the hospital, where he died shortly thereafter, according to the police.

Insufficient

Prosecutor Mike Freeman said, "Former police officer Derek Chauven was charged with unintentional murder by the Hinpin District Prosecutor's Office" in connection with the George Floyd case. But this measure was "late", according to the Floyd family, which was also considered insufficient.

The family said in a statement that they wanted "the premeditated murder charge" of that policeman. "We want to see the arrest of the other (police) officers (involved)," she added.

President Donald Trump announced Friday that he had spoken to the Floyd family. "I understand the pain," he said in the White House, adding, "The George family has the right to justice."

For his part, former US President Barack Obama considered that Floyd’s death should not be considered a "normal" matter in the United States.

As for the potential Democratic presidential candidate, Joe Biden, he called for justice and a "real leadership" for the United States, accusing President Donald Trump of encouraging violence after threatening to use military force to end riots in Minneapolis.

Biden added that the frustration, frustration and exhaustion of black Americans are "undeniable", and that the country needs to face its "deep, open wound" of racism.

Pointing to Trump, he said, "This is not the time for flaming tweets. It is not the time to encourage violence." "This is a national crisis and we need real leadership at the present time. Leadership brings everyone to the table so that we can take measures to root out organized racism," he added.

Biden's speech came in response to Trump's tweet in which he said that he could not allow the situation in Minnesota to slide into chaos, and that looting should not be allowed to spoil the peaceful protest.
