The Belfast Islamic Centre has been attacked while some of its members were praying inside the building.

The incident on University Road in the south of the city sparked a security alert on Friday night.

Kashif Akram from the Belfast Islamic Centre told BBC News NI a window had been broken and device thrown inside, while up to 30 people were upstairs praying.

A 34-year-old man has been arrested and remains in custody.

Mr Akram said the attack has caused alarm among the Muslim community.

“There was a lot of commotion outside, that’s when people realised from upstairs that something was happening outside. Thankfully nobody was hurt.”

He added: “They were very angry, very upset, they were here to do their prayers, minding their own business.”

He praised the fast response of the security workers at the building, and the police.

“Unfortunately, the place was cordoned off last night and we couldn’t continue with our congregational prayers last night or this morning.

“Thankfully, the building is back in operation since six this morning, everything has been cleared and we’ll be fully functional today.”

Raied Al-Wazzan, a former treasurer of the Belfast Islamic Centre, said the centre and some neighbouring properties had been evacuated when he arrived.

Having spoken to security at the centre, he said he understood someone had tried to enter the building via the front door but was turned away.

“He was trying to get in and security stopped him. He was carrying a bag on his back and… also carrying a brick.”

Mr Al-Wazzan said the person then walked to the side of the building and smashed a ground-floor window with a brick.

At this point, it is reported that a passer-by interrupted the incident.

“I’ve seen video footage of a passer-by try to stop the perpetrator,” Mr Al-Wazzan said.

“He tried to protect the centre actually and we thank that gentleman and we hope we could find him and thank him in person.”

Alliance assembly member Paula Bradshaw said: “This is just the latest example of an attack motivated by hate which does not reflect the diversity of south Belfast in 2025,” she said.

“This attack was again designed to cause fear among people inside the centre, who were at prayer at the time.”

Sinn Féin’s Deirdre Hargey condemned what she called a “sinister” attack.

“No one should ever feel unsafe in their place of worship, and my thoughts are with everyone affected,” she said.

“Acts like these, fuelled by hate, spread fear and division, and target people who have come to our communities to build a life and call this place home.”

Green Party councillor Áine Groogan said it was “another reminder of the very real danger faced by our Islamic community”.

“The recent rise in racist hate and violence on our streets is a shameful stain on our society,” she added.

“We must all take responsibility for actively challenging racism, misinformation, and bigotry wherever it appears before someone is seriously hurt.”

The Police Service of Northern Ireland (PSNI) said a number of cordons were in place over night during the alert.
