UK authorities have blamed far-right activists for stoking anger on social media following a brutal Belfast stabbing

Police used water cannon late Wednesday to disperse small crowds who had gathered for a second night in Northern Ireland as UK authorities blamed far-right activists for stoking anger on social media following a brutal Belfast stabbing.

Police boosted their presence on the city streets, but while the main flashpoints of 24 hours earlier appeared quiet, dozens of men confronted police in one area, throwing missiles like rocks and bottles and setting fires in the middle of the road.

A line of police vans, backed by police in riot gear, were trying to push the crowd back at a roundabout to the north of Belfast, AFP images showed.

“Crowds have gathered & missiles are being thrown at officers who have now deployed the water cannon in an attempt to maintain public order,” the police said in a statement, urging motorists to avoid the area.
