24 hours in Northern Ireland during 'The Twelfth' which is the most important date in the Orange Order calendar and marks the anniversary of King William's Battle of the Boyne victory. Bonfires are set on fire the night before Orangemen and women parade across the Province. Police prevent the Belfast parade passing the Catholic Ardoyne which is a known flashpoint and are then caught between Loyalist and Nationalist demonstrators. This year a young woman was run over and seriously injured when a driver drove his car through Nationalist protesters, but most of the parades passed off peacefully.
