Thousands of UK riot police braced for more potential outbreaks of violence, which erupted more than a week ago after three children were murdered.
Far-right groups have planned demonstrations in more than 30 locations, with immigration lawyers and buildings hosting asylum seekers set to be the primary targets, a post on Telegram app leaked to the British media revealed.
The government has said 6,000 specialist police are being prepared to deal with England’s worst disorder in over a decade, which has seen hundreds arrested and more than 100 charged.
The violence broke out after three girls, aged nine, seven and six, were killed and five more children critically injured during a knife attack at a Taylor Swift dance class in Southport, north west England.
The suspect was identified as 17-year-old Axel Rudakubana, born in Wales.
UK media reported that his parents are from Rwanda.
Despite the police statement, initial disturbances in Southport centred around a local mosque, and widespread violence has rocked England and Northern Ireland since on Wednesday.
Prime Minister Keir Starmer warned that anyone involved would face “the full force of the law”, including those inciting violence online.
“That should send a very powerful message to anybody involved, either directly or online,” he added in televised comments.
The unrest, Britain’s worst since the 2011 London riots, has led a number of countries to warn its citizens about the dangers of travelling in the United Kingdom.
