Seven police officers were slightly injured on the second night of disturbances in Belfast surrounding the marches of the Protestant Orange Order brotherhood, security officials said Sunday.

Young protesters threw bricks, bottles and other objects at officers in the northern part of the capital of Northern Ireland at the same spot where on Friday 32 officers were injured in earlier violence.

The police used powerful water cannons to control the protests on Saturday night, a police spokesman said, adding that the incidents that did arise were "isolated."

The first disturbances began Friday night in Belfast after police prevented organizers and protesters from passing alongside a nationalist - or Catholic - neighborhood.

Just like every year on July 12, members of the Orange Order march through the streets of the province to commemorate the 1690 victory of Britain's Protestant King William of Orange over the Catholic he dethroned, James II, in the Battle of the Boyne near Belfast, marches that often pass through or very near nationalist areas.

Many young protesters expressed their discontent and anger after the so-called Parades Commission, which makes the final decision about the route the hardline Protestant Orangemen marchers may take, decided for the first time to prevent them from skirting the neighborhood of Ardoyne, a militant Catholic zone in northern Belfast.
