Serious rioting erupted last night in the Ardoyne area of north Belfast. The trouble broke out after police in riot gear took up position ahead of an Orange parade walking past the Ardoyne shops on Tuesday evening and spread across the city.
Here, police try to break into a burning car. Unionists insist that the violence had nothing to do with the parade, but was caused by militant Republicans protesting against it.

Stones, bottles and fireworks were thrown at police. Water cannon was used to push back the crowd of about 200 people.
According to police, a number of officers were injured. Police also fired a number of plastic bullets and a photographer was hit.
