Sectarian violence erupted for a second night in Northern Ireland, where a press photographer was shot in the leg.
Police said around 700 people threw fireworks and petrol bombs in the capital Belfast.
The clashes come at the start of Northern Ireland’s marching season, a time of annual parades by Protestants which has triggered violent protests by Catholics in the past.
On the previous night youths fought in a Catholic enclave within the predominantly Protestant east side of the city.
Police have blamed the pro-British paramilitary Ulster Volunteer Force for initiating that incident.
