Sporadic violence broke out during a loyalist parade in Derry today.
Riot police moved in after a crowd of nationalists attacked the Apprentice Boys Parade in the centre of the city.
The trouble erupted as the parade was making its return journey. Police baton charged around 80 nationalists who hurled bricks and bottles.
A number of people were injured during the clashes.
A police spokesman confirmed that a total of eight people were arrested forpublic order offences. During the rioting, nationalist youths set fire to a carin Lower Magazine Street.
The spokesman said the city was relatively quiet but crowds have continued togather in the nationalist Bogside area.
Around 2,000 loyalists took part in the parade.
Police had erected large plastic screens at the Diamond in the centre of the city to divide nationalist protesters from marchers.
Despite discussions between the Apprentice Boys and the Bogside Residents Group, there had been fears of violence because the march coincided with the Old Firm derby between Rangers and Celtic.
