A number of people have been arrested after violence erupted following a parade by loyalists in the North.
Police said the demonstration by the Apprentice Boys in Derry had passed off largely peacefully, apart from six arrests for public order offences.
A petrol bomb was thrown at police in Fahan Street and a stone-throwing incident took place at Butcher Gate. A number of petrol bombs were recovered by officers from the Fahan Street area of the nationalist Bogside.
Up to 10,000 members of the Loyal Order and 130 bands took part.
The arrests follow separate disturbances in which 50 petrol bombs were thrown at police in the area last night. During the violence two stolen cars were burned at an area known as Free Derry Corner in the Bogside.
The Apprentice Boys were marching to celebrate the victory of the Protestant Prince William over the Catholic forces of King James in December 1689.
The Apprentice Boys and the Nationalist Bogside Residents’ Group had appealed for trouble-makers to stay away from the parade.
Police have said they are pleased that the main parade was peaceful.
