Nationalist youths throw bottles at police officers after the annual Orange march on July 12, 2016 in Belfast, Northern Ireland. The controversial Ardoyne interface is a flash point between the Catholic and Protestant communities with trouble flaring in the area frequently during the so called marching season. The Protestant Orange bands from the nearby area have been stopped from parading past the Catholic Ardoyne for the past three years. The Orange marches and demonstrations celebrate the Battle of the Boyne in 1690 when the Protestant King William of Orange defeated the Catholic King James II on the banks of the river Boyne.
