Home Secretary Priti Patel says she is “disgusted” by violence directed against police by “thugs” during another protest in Bristol on Friday evening.
She tweeted: “I have no doubt that the silent, law-abiding majority will be appalled by the actions of this criminal minority.
“Despite repeated warnings to disperse, it is clear that these thugs were only intended to cause trouble. I receive regular updates and the police have my full support.”
Prime Minister Boris Johnson described the protesters as “a mob intent on violence”.
He condemned the incident and tweeted: “There were shameful attacks against police officers in Bristol last night. Our officers shouldn’t have to deal with bricks, bottles and fireworks being thrown at them by a mob intent on violence and property damage.
“The police and the city have my full support.”
Ten people were arrested during the demonstration, Avon and Somerset police say.
The troop said glass bottles and bricks were thrown at officers, fireworks were fired in the mounted division, with a horse covered in paint.
Superintendent Mark Runacres said, “The majority of the people acted peacefully, but there was a minority who were hostile to the officers.
“Three of those arrested were arrested on Sunday in connection with the violence.”
