Nationalist youth throw petrol bombs at police in Northern Ireland

Ten police officers were injured after petrol bombs, fireworks and heavy masonry were thrown during disorder in Londonderry. One person had been arrested as of the early hours of Sunday, after police brought in their Public Order Dog Unit and warned that the unrest in Nailors Row presented a serious risk to the safety of residents in the area. The violence broke out on Saturday afternoon at the end of the Apprentice Boys of Derry parade, an annual march which marks the anniversary of the ending of the 1689 Siege of Derry. The perpetrators were nationalist youths, the BBC reported. William Calderwood, the Superintendent of Derry City and Strabane, called the incident disgusting as he promised a robust investigation is underway to bring all those responsible for this violence to justice.
