In Dublin, Ireland, hundreds of far-right protesters fought street battles with police on Thursday in riots that erupted after a knife attack at a school that left five people injured, including three children. Police say the rioters were driven by misinformation about the knife attack, which was blamed on an immigrant. The BBC reports the attacker was in fact an Irish citizen who has lived in Ireland for 20 years. Anti-immigration protests erupted in Ireland this year after the government received more than 140,000 immigrants, its highest total in 15 years.
