Protesters set fire to a bus in the city and firefighters had to remove residents from their homes in another street after flames spread to properties.
More than 200 masked men and youths broke off from a main gathering in Cloughfern to torch the bus, while several cars were seen ablaze later into the evening.
Fire crews fielded 256 calls and reported to 62 incidents, the majority of which were in Belfast.
In the east, masked groups have approached locals with cameras â as well as a GB News crew â urging them firmly to leave and stop recording.

Further afield, demonstrations are underway across Northern Ireland â with protests also unfolding in cities in Britain.
Police and politicians have pleaded for calm after Monday nightâs attack, which has seen the 30-year-old migrant charged with attempted murder, making threats to kill and possession of a bladed article in a public place.
The charges mean reporting restrictions around the attack are in place.
Police Service of Northern Ireland (PSNI) Assistant Chief Constable Ryan Henderson said âsporadic pockets of disorderâ have broken out in a number of locations across Northern Ireland.
âWe are urging everyone to remain calm, act responsibly, and avoid any activity that could place themselves or others at risk,â he said.
The PSNI deployed its Tactical Support Group units and arranged for a helicopter to oversee the response following reports of demonstrations across Ulster tonight.
Though unlike in protests seen in Britain, police presence has been intentionally limited around Belfast in a bid to cool the risk of violence.
Protesters assembled in other corners of the province, including Antrim and Londonderry.
Democratic Unionist Party MLA Paul Givan, who attended a peaceful protest in Lisburn, urged demonstrators not to âdistractâ from their concerns about uncontrolled immigration.
He said: âIt is important that people do conduct themselves in a peaceful manner to make sure that the key issues here around immigration can be heard and we are not distracted by any form of violence.
âThat will only distract. People should express their views in a peaceful manner.â
Late on Tuesday, Northern Irelandâs First Minister Michelle OâNeill â who earlier accused GB News of âfake newsâ â described scenes of violence in Belfast as âoutright thuggeryâ.

She said: âGroups of masked men burning families out of their homes is nothing less than disgusting cowardice.âThis has nothing to do with community. This is outright thuggery. The attack in North Belfast was heinous and wrong.
âBut there are dangerous attempts to exploit that to target and attack innocent people who are simply trying to live, work and raise their families here. Racism, intimidation and violence are wrong wherever they occur.
And Arlene Foster, the former First Minister said she watched the unrest âwith great sadnessâ.
âThis is not only wrong â we condemn the violence absolutely â but itâs counter-productive,â she told Sky News.
A separate protest took place in Southampton, where demonstrations took place last week following the murder of 18-year-old finance student Henry Nowak.
London and Glasgow also witnessed protests in connection to the incident in Northern Ireland.
The 30-year-old suspected attacker entered Northern Ireland by crossing over from the Republic of Ireland in 2023.
He made the journey to the UK after leaving Sudan and eventually arriving in France.
However, the Home Office quickly approved his asylum claim shortly after arriving in Northern Ireland and granted him leave to remain in the UK until 2028.
He is due to appear at Belfast Magistratesâ Court on Wednesday.
The alleged victim, who was identified as a man in his 40s, suffered injuries to his eyes, back and face.
Despite the alleged attacker crossing over from the Republic of Ireland, Dublinâs Department of Justice said it was ânot in a position to commentâ.
