Mark News, Sky News home affairs correspondent, said: “A very serious escalation of the disorder is now in Whitehall, outside of Downing Street.
“Metropolitan police have just brought in officers on horseback who have just mounted a load in Whitehall from the war memorial to the cenotaph.
“You can see that one of the officers was knocked over from his horse, that horse has now bolted.
“There are bottles and other things thrown at officers on horseback.
“At Downing Street, the other police officers guarding the doors across from Downing Street put on a full riot kit and also took out their riot shields. ”
Videos circulating on social networks seem to show that missiles are launched at police officers in protective gear, while police on horseback have pushed protesters along Whitehall.
A bicycle was also allegedly thrown at a police horse.
An officer appeared to have fallen from his horse, which then bolted – sending crowds of people dispersing.
According to the Daily Mail, red flares were launched at the security doors of Downing Street.
Missiles were said to have been launched at officers for about ten minutes, including fireworks and firecrackers.
It is understood that a man was arrested on Parliament Square.
Earlier in the day, the statue of Winston Churchill in Parliament Square was vandalized while thousands of people attended a Black Lives Matter rally.
Police surrounded the monument after green graffiti was scrawled on it earlier today.
The photos show demonstrators climbing on the statue while holding signs.
It comes after a largely peaceful protest that started earlier on Saturday afternoon.
Hundreds are silent and kneel while raising a fist in the air.
The crowd then started chanting “no justice, no peace” and the name of George Floyd.
Photos show that the majority of demonstrations wear face masks, while others use gloves and hand sanitizer.
Many people wore masks and measures of social distancing were promoted at events in London, Manchester, Cardiff, Sheffield and Newcastle, among other cities.
Signs carried by protesters referred to the coronavirus crisis, one of which said, “There is a virus bigger than Covid-19 and this is called racism. ”
At the start of the rally, an organizer used a megaphone to say to the crowd, “We are not here for the violence.
“Today is pure positivity, today is pure love. ”
Protester Bobbi, 26, of Chingford, London, who did not give his last name, said, “We literally live in history books, we are going to talk about it to our future children and I mean that I was here to support this. ”
Thousands of protesters invaded central Manchester. They chanted and cheered in unison and held homemade signs with the initials BLM.
Several hundred walkers gathered in Newcastle, while thousands more watched an online demonstration in the north-east of England.
Protesters gathered at the Earl Gray monument in the city center were given masks if they did not have them, while hand sanitizer was available.
Dr. Christina Mobley, a lecturer who came to the University of Newcastle from the University of Virginia in Charlottesville, attended her five-year-old daughter.
The historian, who heads the decolonization project for the university program, said: “I really felt the need to be here today. The organizers have done an incredible job.
“It is really powerful to see such a young and motivated crowd going out and organizing, distributing masks and working with the police. ”
She took a photo of one of the officers who removed his helmet during Mr. Floyd’s silence.
At the same time, an online demonstration organized by Stand Up To Racism – North East attracted several thousand people, who listened to speakers including Janet Alder, whose brother Christopher died in police custody in Hull in 1998.
In Sheffield, hundreds of people gathered on Devonshire Green to protest and remain silent for a minute.
During the rally, which included speeches, they chanted, “No justice, no peace, no racist police.”
Saturday’s protests reflect global anger over police treatment of ethnic minorities, sparked by the murder of Floyd on May 25, when a detained white policeman knelt on his neck for nearly nine minutes while his colleagues were waiting.
