Riots raged in Belfast, the capital of Northern Ireland, for a second night, with masked men in balaclavas targeting ethnic minorities after a "hit list" of homes housing foreign nationals was circulated.
The disorder was triggered by a knife attack on Monday allegedly carried out by a Sudanese asylum seeker, who has been charged with attempted murder.
Hadi Alodid, a 30-year-old granted indefinite leave to remain in the UK, allegedly attacked a man on a residential street with a knife in what many commentators have described as an attempted beheading.
The victim, a man named Stephen Ogilvie, lost his left eye and suffered serious cuts to his face. His family said in a statement on Wednesday that "we have many migrants who make a deeply valuable contribution to our country. We do not want this terrible tragedy to divide people and fuel hostility."
Riots first broke out in Belfast on Tuesday night, as hundreds of masked men torched homes and vehicles belonging mostly to ethnic minority residents.
On Wednesday evening, masked rioters fought with police near a hotel accommodating migrants in northern Belfast.
The Police Service of Northern Ireland (PSNI) said it was contacted by several "extremely distressed" families whose homes were on a hit list circulated among rioters.
The PSNI warned that people sharing the document "may be committing a criminal offence".
Footage on Wednesday showed police officers firing a water cannon and plastic bullets at rioters, who tore bricks from properties to throw at buildings and officers.
Rioters were seen trying to set an abandoned building on fire. Others set wheelie bins alight.
Streets across Belfast were blocked off by rioters, and masked men set up checkpoints to monitor passing cars for non-white people.
They did this with makeshift roadblocks made of street furniture. Men were filmed looking into cars before allowing them to pass.
'This has nothing to do with community. This is outright thuggery'
On Tuesday, rioters had sought out homes of those believed to be migrants, asylum seekers or refugees.
Footage showed children being carried out of houses next to the ones set alight.
A Middle Eastern supermarket was set on fire and a local pastor, Jack McGee, told the BBC that residents were forced out of their houses "because they're black".
Men filmed kicking in doors and smashing windows said they were "getting foreigners out".
Anti-migrant protests were held elsewhere in the UK on Tuesday night, including in Glasgow, where 300 men in balaclavas were seen marching through the streets and attacking passers-by.
Muslim worshippers had to be locked in the city's Central Mosque for their safety by police as men surrounded the building.
British Prime Minister Keir Starmer denounced disorder as "shocking and completely unacceptable" on Wednesday morning.
