Vehicles have been set alight and fireworks thrown at police in violent clashes in Dublin.
The Irish police chief has blamed the unrest on a “lunatic, hooligan faction”, which follows an earlier knife attack in Ireland’s capital city.
The justice minister has accused those involved in the violence of using the earlier incident to “wreak havoc”.
Videos shared on social media showed a police car, a tram and a bus among the vehicles set on fire. In another video people could be seen throwing fireworks at police.
