The unrest has prompted India, Australia, Nigeria and other countries to warn their citizens to stay vigilant.
Saminata Bangura, a 52-year-old support worker in a care home in Liverpool said she had felt so welcome in Britain after she moved from Sierra Leone. But she was now scared and largely staying at home.
"I'm so scared, even when I'm walking now, because everywhere, we're scared, especially, we Blacks," she said, describing how a library was vandalised near where she lives.
RACIAL HATRED
Starmer has vowed a reckoning for those who have engaged in rioting, hurling bricks at the police and counter protesters, and looting shops and burning cars.
Police on Tuesday charged a 28-year-old man with stirring up racial hatred over Facebook posts linked to the disorder. A 14-year-old pleaded guilty to violent disorder.
On Monday night, trouble flared in Plymouth, southern England, and again in Belfast in Northern Ireland, where hundreds of rioters threw petrol bombs and heavy masonry at officers and set a police vehicle on fire.
Police have blamed online disinformation, amplified by high-profile figures, for driving the violence.
At the end of December 2023, there were 111,132 individuals in receipt of asylum support in Britain, with 45,768 people in hotels. During that year, the government's statistics office estimates that net migration to the country was 685,000.
Experts on extremism and social cohesion say far right agitators have used the Southport killings to spark violence.
Sunder Katwala, director of the think tank British Future, which focuses on migration and identity, said the killings had been used "to mobilize against, particularly asylum seekers and Muslims, and that has continued, after the evidence which is that the person is neither an asylum seeker, nor a Muslim."
The police have said the attack was not terrorism-related and that the suspect was born in Britain. Media reports have said the suspect's parents moved to Britain from Rwanda, a majority-Christian country.
In a YouGov poll on Tuesday, three quarters of respondents said the rioters did not represent the views of Britain as a whole, with 7% saying they supported the violence.
