Belfast: Rioting 'was worst seen in Northern Ireland in years'

Rioting in Belfast on Wednesday night was on a scale not seen in Northern Ireland for years, police have said. During several hours of violence, police officers were attacked, petrol bombs were thrown and a bus was burnt. Eight officers were injured at an interface between loyalist and nationalist areas in west Belfast. Northern Ireland's power-sharing executive said it was "gravely concerned" by recent street violence and has called for calm to be restored.
