Clashes broke out at an anti-Islam rally in the Norwegian capital of Oslo on Saturday, when an anti-Islam protester ripped pages from Holy Quran.
The rally, organized by the group Stop Islamization of Norway (SIAN), took place near the parliament building.
As being reported, clashes then erupted, with counter-protesters throwing eggs at SIAN members and attempting to jump police barricades.
The clashes prompted authorities to end the event early.
Hundreds of counter-protesters also gathered, banging drums and chanting “No racists in our streets,” reported news agency DPA.
The situation came to a head when a female member of SIAN ripped pages from the Quran and spat on them, according to the news agency NTB.
The authorities arrested nearly 30 people, several of whom were minors, Norwegian public broadcaster NRK reported and used pepper spray and tear gas to keep the rival groups apart.
