Police have been pelted with bricks and bottles after violence flared following an Orange Order parade in Belfast.
The trouble began when police blocked the parade from marching through a controversial stretch of the Crumlin Road.
A crowd of nationalists gathered in protest at the march as it approached police lines. Empty bottles, bricks and metal bolts were thrown at police, reports the Huffington Post.
Violence escalated when an out-of-control car struck pedestrians in nearby Ardoyne, trapping a girl underneath and injuring a number of people.
The girl was treated by paramedics at the scene before being taken to hospital, where it is now understood she is in a stable condition.

At least eight officers from the Police Service of Northern Ireland (PSNI) were injured in the violence.
The Crumlin Road has a history of violence and was the scene of a number of killings during the Troubles.
Northern Ireland Secretary Theresa Villiers described attacks on police as "disgraceful", adding: "Those responsible do nothing to further the cause they claim to promote. They damage Northern Ireland and wreck a day which should be about respectful celebration of cultural tradition."
A spokesperson for the Orange Order's Grand Lodge said: "Those involved in violence should desist. It is not only counterproductive but also plain wrong. Such actions are only strengthening the hand of those who wish to further curtail our parades.
