A police cordon seperates nationalist protesters and a parade by the unionist Orange Order at the Ardoyne shops on the Crumlin Road in north Belfast on October 1, 2016. The march, which went off peacefully, was given the go-ahead to pass along the Crumlin Road, a bitterly contested boundary between unionists and republicans, by the parades commission. Serious violence has flared in the area for several years, with police previously bombarded with bricks, bottles and petrol bombs from both sides of the sectarian divide. / AFP / PAUL FAITH (Photo credit should read PAUL FAITH/AFP via Getty Images)
