The Police Service of Northern Ireland (PSNI) has condemned the scenes of violence and disorder on "the streets of Belfast" on Saturday.
The trouble happened after anti-immigration and anti-racism protesters faced off in tense scenes outside the city hall.
Police are treating damage to several businesses as hate crimes.
The PSNI said four people have been arrested after 13 reports of criminal damage and five of arson.
Three police officers were injured during the disorder - two remained on duty while the third was relieved from duty after suffering concussion.
After the protest outside the city hall some anti-immigration protesters had attempted to march to the Belfast Islamic Centre in south Belfast but were prevented by police.
The crowd then made their way to Botanic Avenue, University Street, Lower Ormeau, Holylands and Donegall Road areas where sporadic violence developed for a number of hours.
Disorder also broke out in the Sandy Row area where a business premises was set on fire
'Devastating impact'
Assistant Chief Constable Davy Beck said those who "engaged in this behaviour bring nothing but shame to themselves and Belfast city".
“This disorder, violence and destruction has no place in Belfast or anywhere else across the streets of Northern Ireland," he said.
“I would strongly urge anyone who was involved in yesterday’s rioting and disorder to think long and hard about their actions and the devastating impact this has had on local communities."
A supermarket and a cafe in south Belfast were badly damaged by fire in overnight attacks.
'Everything we built is destroyed'
Abdelkader is the owner of the supermarket in the Donegall Road area that was attacked.
He said he had shut the shop on Saturday afternoon and was surprised to see images of it burning on social media later that night.
He said he was from Syria and had been living in Northern Ireland for eight years.
“Everything we built from zero is destroyed,” he told BBC News NI.
“Everything is done, my life is done.”
He said he did not have the financial means to rebuild the property.
'Community is very afraid'
Sam Yousef is a representative of the Syrian community in Belfast.
He says that members of the community are “very afraid” and that he feels a bit unsafe as well.
Mr Yousef says that on social media he has seen people telling each other not to leave the house because the situation is “very terrible”.
“This is our country…we are trying to pay back, trying to work hard, pay tax, integrate into the society and contribute to the people here," he said.
“Our children are growing up here and we want them to feel safe because we escaped an unsafe area."
Daniel Lannon, who attends a nearby church, said he was driving past on Sunday morning when he saw the destruction caused by the attack on the supermarket.
He stopped to help with the clear-up.
“I believe this is the right thing to do,” he added.
“Some of the stuff that was going out on social media, with the protesters saying they were doing this in the name of Christianity, but that’s not Christianity.
“Christianity is to love your neighbour, to help them, to help those who are different from you, so that’s what we are trying to do today.”
'I could have been killed'
A cafe on Botanic Avenue was attacked by a crowd of anti-immigration protesters on Saturday afternoon as they made their way to the Holylands area of south Belfast.
Protesters threw missiles at members of the media.
Windows were smashed and furniture was broken in the cafe on Botanic Avenue.
Rahmi, the owner of the cafe, who has been in Belfast for 35 years, told BBC News NI on Sunday that he "could have been killed".
He reiterated that there could have been more of a police presence when "the parade was walking" through the area.
“You watch the videos and you can see only me and these big, massive chairs that they keep throwing at me.
“I’m sure if I had left the door open, they would do more damage or burn the inside.”
On Saturday, the police said it was aware of a number of reports of criminal damage and were treating them as hate crimes.
'Intimidation and intolerance'
Northern Ireland's Justice Minister, Naomi Long, condemned the violence.
"There can be no place in our community for hate: for xenophobia, racism and Islamophobia," she added.
"Neither can there be any place for such intimidation and intolerance.
"My thoughts are with all those impacted by this disorder; those whose property was damaged, businesses attacked and who were intimidated, threatened or fearful as a result."
More than 100 people have been arrested after demonstrations organised by far-right groups descended into riots in UK towns and cities on Saturday.
There was unrest in Hull, Liverpool, Bristol, Manchester, Stoke-on-Trent, Blackpool, as well as Belfast, with missiles thrown, shops looted and police attacked in some places. Other smaller demonstrations elsewhere did not turn violent.
Prime Minister Sir Keir Starmer has pledged to give police forces the government's "full support" to take action against "extremists" attempting to "sow hate".
