In northern Ireland, thousands of Protestants are marking the contentious Apprentice Boys Parade, marching through the mainly Catholic area of Londonderry. <br /><br />The march, which has sparked unrest in the past, is symbolic of the fragile peace in Northern Ireland. <br /><br />Protestants in the historically divided region want closer ties with Britian, while most Catholics favour a united Ireland. <br /><br />Al Jazeera's Tania Page reports from Belfast, where a similar but smaller march has taken place.
