DAYS of violent protest in Northern Ireland claimed their first fatality yesterday. Dermot McShane, 35, died from head injuries sustained on Thursday in a Londonderry protest at Protestants being allowed to march through a Catholic area of Portadown. Sinn Fein negotiator Martin McGuinness claimed McShane had been run over by a British Army Land-Rover. Sinn Fein president Gerry Adams said a police U-turn over a ban on the Protestant Orange Order parade in Portadown was like letting 'the Ku Klux Klan go into Harlem'. Irish Foreign Minister Dick Spring said the police U-turn had left Catholics feeling betrayed by the police and the British Government. Irish Prime Minister John Bruton accused Britain of bowing to Protestant pressure and discriminating against Catholics, and said London was to blame for the violence. Britain's Northern Ireland Secretary, Sir Patrick Mayhew, called Mr Bruton's claims 'offensive'. Republican gunmen shot at police in Belfast yesterday. Mobs roamed city streets setting light to makeshift barricades to draw in police and pelt them with petrol bombs and stones. The bitterness spilled over to the Spanish holiday island of Tenerife, where 300 Irish Protestant and Catholic and English tourists fought a street battle with bottles, glasses, knives and iron bars after an argument in a bar about the political situation in Ulster. Four policemen were hurt.
