Around 26 police officers have been injured in overnight violence in Belfast.
The officers came under attack from republicans and loyalists during violence linked to a nationalist parade.
It happened in an area in the north of the city.
Stones and bottles were thrown at police as they intervened in the violence.
3 officers have been treated in hospital.
Tensions had been simmering in recent days over trouble close to a Catholic church not far from the parade yesterday.
