Ireland witnessed its worst civil disorder in decades after rioters marauded through Dublin city center looting shops and setting buses and police cars on fire in a spate of violence that appeared to be triggered by a stabbing attack that injured three children, 

Irish police said Friday that 13 shops were damaged and 34 people arrested following the riots, which followed the attack by an unidentified man outside a school on Thursday afternoon. Garda Commissioner Drew Harris said on Friday that he had not seen such levels of violence “for decades.” He added that it had been caused by a “lunatic, hooligan faction driven by far-right ideology.”
