Water cannons used in Belfast after flag protest

Loyalists and nationalists have clashed in east Belfast after a union flag protest in the city centre on Saturday.

It happened as loyalists returned from a demonstration at city hall, against the council's decision to limit the number of days the union flag is flown.

Rocks and fireworks were thrown at Albertbridge Road, near the nationalist Short Strand. Police used water cannons and fired at least one plastic bullet.
