(CNN) -- Cars set alight. Petrol bombs hurled at police and at peace walls. A double decker bus hijacked, and water cannons unleashed on protestors for the first time in six years.
The disorder that has shaken parts of Northern Ireland over the last two weeks has highlighted the fragile peace that binds together the region's diverse community of loyalists and nationalists, more than 20 years after the Good Friday Agreement.
Loyalists want Northern Ireland to remain part of the United Kingdom, while nationalists would like to see Northern Ireland become part of the Republic of Ireland.
The first few nights of violence began after youths in a loyalist pocket of Derry/Londonderry launched a petrol bomb at police officers who had tried to break up their gathering.
