Violence has erupted in London after a group of Black Lives Matter protesters clashed with the police – with bottles thrown and mounted officers charging down Whitehall.
It came after a largely peaceful day of demonstrations against racism across the UK following the killing of George Floyd in the US.
Sky News correspondent Mark White was at the scene on Whitehall – near Downing Street and The Cenotaph.
He said the atmosphere had started to shift in the area, where around 400 to 500 people had gathered, and then “just after the thunderstorm… the crowd started throwing bottles and other objects at the police”.© Getty Police tried to hold back the crowd on Whitehall, close to The Cenotaph and Downing Street
Mounted officers charged down the street at around 6pm to push the protesters back.

Metropolitan Police said she had been taken to hospital, where her injuries are not said to be life-threatening.
The force tweeted: “The officer fell from her horse, and we are examining the full circumstances of what took place.”
Police said the horse, which was uninjured, made its own way back to its stables nearby.

Protests remained peaceful in the day, before tensions escalated between police and a small number of activists in the evening.

One protester told Sky News he was angry some of those at the rally had turned to violence, saying “the meaning’s become lost”.
The man said: “People are here, throwing bottles, doing all sorts of things, that is eventually going to tarnish why we’re here. It’s going to make us look like the bad people here.”© Reuters George Floyd’s coffin arrives for a memorial held in his home town

He added: “To the tiny minority who were violent and threw glass bottles and lit flares – you endangered a safe and peaceful protest and let down this important cause.
Home Secretary Priti Patel said violence towards police was “completely unacceptable” and gave officers her full support.
In a tweet, she said: “Protests must be peaceful and in accordance with social-distancing rules. Violence towards a police officer is completely unacceptable at any time.”
