BELFAST (Reuters) - A woman was injured in an explosion in the Northern Irish town of Lurgan on Monday, police said. There was no immediate indication of how badly the woman was injured. "There are first reports of an explosion at a car in the Shore Road - Lake Street area of Lurgan," a spokesman for the Royal Ulster Constabulary (RUC) told Reuters. The spokesman said a British army bomb disposal expert had been sent to the scene. Northern Ireland is experiencing an uneasy peace following the so-called Good Friday agreement which rival parties signed last year in a bid to end 30 years of guerrilla and sectarian strife. Republican dissidents opposed to the plan set off an explosion which killed 28 civilians in the town of Omagh last August. In recent months several pro-British Loyalist groups who are critical of the accord have launched attacks on Catholic nationalists.
