Bombs hit Londonderry in Northern Ireland by: From correspondents in Dublin From: AP January 20, 2012 11:19AM TWO bombs planted by Irish Republican Army dissidents have detonated in the Northern Ireland city of Londonderry, but no injuries were reported as police quickly evacuated the area following phoned warnings. Martina Anderson, a former Irish Republican Army member who represents Londonderry for the Irish nationalist party Sinn Fein, said one bomb left outside the city's main tourist office exploded as about 75 elderly residents of a nursing home were still being evacuated about 25 metres away. She said IRA dissidents "need to come forward and explain how they believe this achieved anything, other than the disruption of vulnerable old people's lives". Chief Superintendent Stephen Martin, the police commander in Northern Ireland's second-largest city, said much of central Londonderry would be sealed off tomorrow so that police could comb the bomb sites for forensic clues.
