Bomb threats cripple Dublin-Belfast travel
Dublin - Police have closed the main road and rail links on the Irish border between Dublin and Belfast because of dissident IRA bomb threats and the discovery of an abandoned van.
Friday's security alert is causing major travel disruption between the capitals of the Republic of Ireland and Northern Ireland.
Irish Republican Army splinter groups opposed to peacemaking in Northern Ireland have repeatedly placed bombs and hoax devices near the parallel road and rail lines south of the border town of Newry.
Police say a dissident IRA caller made two telephoned bomb warnings on Thursday night.
Police shut the M1 motorway for a 15km stretch and forced drivers to take lengthy detours. Train passengers also were required to cross the border by bus.
