Thugs behind violence which flared in Belfast brought shame on themselves and the city, a senior police officer said today.

Four people have been arrested after a day and night of sporadic violence which saw a cafe and shop set on fire. Cars and bins were also torched in the Sandy Row area.

Three PSNI officers were injured and at least 13 reports of criminal damage made to police.

Petrol bombs were thrown and an apartment block evacuated at one stage, Assistant Chief Constable Davy Beck said.

He said police will use “every tool at our disposal to identify those involved”.

Fresh trouble flared on Saturday night after rival groups faced off in the city centre earlier in the day, as unrest following the killing of three young girls at a Taylor Swift-themed dance party in Southport spread to Northern Ireland.

At one stage police formed a large cordon around the Islamic Centre on University Street as an anti-immigration march headed towards the area.

“Nothing left just ashes” – Businesses destroyed during night of racist disorder in south Belfast

There has been widespread condemnation, with political leaders saying those responsible must face heavy punishment.

Justice Minister Naomi Long said: “These demonstrations were orchestrated by those motivated by a desire to create fear and division. They have no regard for human life and are focused on spreading misinformation and disinformation to alienate some sections of our community.

“This type of disorder needs to be highlighted for what it is – fearmongering and intimidation of the highest level.

“There can be no place in our community for hate: for xenophobia, racism and Islamophobia. Neither can there be any place for such intimidation and intolerance.”

Mr Robinson, the DUP leader, said: “The scenes of violence, thuggery and destruction in Belfast yesterday are totally unacceptable. Lawlessness and violence was and is always wrong.

“Those intent on such behaviour must face the full rigours of the law.”

Deputy First Minister Emma Little-Pengelly said: “Northern Ireland must always be a place that protects the right to protest, the right to have a view and to express it.

“Let’s be very clear – violence is not acceptable. It never was and it is not now. No one has the right to express hate and violence. Stop it now.”

Secretary of State Hilary Benn posted on X: “Shame on those involved in violent disorder in Belfast today. Hatred has no place in our society. I commend the officers of the PSNI for everything they have done to keep people safe.”

UUP leader Doug Beattie called the scenes “absolutely appalling”, adding: “Those who incited this, not just the perpetrators, must be held to account.”

SDLP South Belfast MLA Matthew O’Toole said: “To see far right thugs – many of whom had no connection to the area – rampage through Botanic Avenue and the Holyland, areas proud of their diversity, was appalling.

“There was nothing legitimate about their actions. They had no cause other than hate and no agenda other than destruction.”

On Saturday, police arrested two people and businesses were attacked, with missiles also thrown at PSNI officers, during trouble linked to an anti-immigration march.

Hundreds of people gathered for the Unity Over Division rally, in support of Muslim communities. Some in the crowd held banners saying ‘no to racism’ and ‘refugees are welcome’.

Soon afterwards, anti-Islamic protesters also gathered near City Hall. Some chanted “Islam out” while others carried a Coolock Says No sign, in reference to a site in Dublin that was being renovated to accommodate asylum seekers.

While the anti-Islamophobia rally ended shortly before 1pm, anti-immigration protesters moved on to south Belfast, arriving on Ormeau Road where around 100 local residents turned them back.

Several businesses around Botanic Avenue were targeted.

Windows were smashed and furniture broken at the Sahara shisha cafe. Its owner Rahmi, who has been in Belfast for 35 years, said he did not “know how to explain” what happened to his children.

Thugs also smashed windows at the Holiday Inn and Dukes at Queen’s Hotel on University Street.

Then, on Saturday evening, cars and bins were torched in the Sandy Row area.

The owner of one supermarket targeted, Bashir, said Muslim businesses were being deliberately targeted.

Firefighters also attended Bash Cafe, which was ablaze.

The Northern Ireland Fire and Rescue Service (NIFRS) said four appliances and two officers attended the cafe on fire. The cause was determined as “deliberate”.

NIFRS then received reports of a shop on fire on Donegal Road shortly after 10.50pm. Four appliances attended before leaving the scene just after midnight. The case was also determined as “deliberate”.

On Saturday, the PSNI said they were treating attacks on businesses as “hate crimes”.

Chief Superintendent Stephen Murray said: “We have dealt with a number of protest sites across Northern Ireland today, including a significant protest and counter protest at Belfast City Hall.

“Many of these caused disruption to the road network. A number of roads, including the M5, Wellington Place and Shore Road were closed for a short period of time.

“We continue to deal with protest activity and sporadic disorder in the South Belfast area and are aware of a number of reports of criminal damage which we are currently treating as hate crimes.

“An investigation has commenced and to date we have made two arrests.

“We would like to thank the community for their patience in respect of the disruption they faced and also place on record our support for the community leaders who worked to resolve the situation.”

Deirdre Hargey, a local Sinn Fein MLA who attended the anti-racism rally, said there was shock that the anti-immigrant protest had been allowed to reach south Belfast.

She told the Belfast Telegraph: “Our understanding is the fascist mob that had gathered at City Hall this morning made their way up towards University Road in south Belfast.”

Ms Hargey said it was “very concerning” that the procession was able to march from the city centre to south Belfast.

She added: “We warned about this yesterday and I spoke to the PSNI and said there was refugee and asylum seeker accommodation the whole way up this route.”

Anti-immigrant protests were also held in Bangor.

Local Alliance MLA Andrew Muir said he was ‘disgusted by the shameful hate marches and protests’.

“Northern Ireland is diverse, open, welcoming and inclusive. Together we must all stand up against islamophobia and any forms of racism,” he added.

Amnesty International’s Northern Ireland director Patrick Corrigan said: “The violence brought to the streets of Belfast today by racist agitators is utterly unacceptable.​”

Anthony Flynn, a local Green Party councillor, posted on X: “Absolutely disgusting scenes from the far-right thugs throwing fireworks, stones, and other missiles towards a peaceful anti-fascist rally. These people are not Belfast. They will exploit any situation to spread their vile hatred.”

Multiple UK towns and cities saw clashes between anti-immigration demonstrators and counter-protesters, with police officers attacked and injured, and many more arrests promised.

The string of violent incidents over the past few days began on Tuesday in Southport, after three girls were killed in a knife attack.

The victims were Bebe King, six, Elsie Dot Stancombe, seven, and Alice Dasilva Aguiar, nine.

Axel Muganwa Rudakubana, 17, from Lancashire, is accused of the attack, but false claims spread online that the suspect was an asylum seeker who had arrived in the UK by boat.

Home Secretary Yvette Cooper said people involved in the clashes “will pay the price” and that “criminal violence and disorder has no place on Britain’s streets”.

Prime Minister Sir Keir Starmer said the police have his “full support” to take action against “extremists” attempting to “sow hate” by intimidating communities as he held emergency talks with ministers over the unrest in parts of England.

Arrests have been made across the country with police warning of more to come once CCTV, social media and body-worn camera footage has been scoured.
