Following two recent attacks by Irish Republican Army splinter groups, Northern Ireland is on edge, fearing a return to violence. Worldfocus.org's weekly radio show explores the history of conflict in Northern Ireland as well as recent violence and life in the province today. Paul Arthur, Kevin Cullen and Honor Fagan join the conversation.

Niall O'Dowd of the Irish America magazine discusses a Real IRA attack on a British base in Ulster on Saturday, the first killings of British security forces in Northern Ireland in a dozen years. The violence threatened the province’s fragile coalition government of Protestants and Catholics.
