Number of arrests after riots in Northern Ireland rises to 19

Police call for calm before anti-racist protests in Belfast and Glasgow as MPs warn of failure over online misinformation

Police said 19 people, including a 16-year-old boy, had now been arrested after two nights of rioting in Northern Ireland following a knife attack earlier in the week.

The violence broke out after far-right activists called for demonstrations in response to the attack, which was captured in a graphic video.
