A suspected Irish Republican Army dissident must stand trial for allegedly murdering 29 people with a car bomb seven years ago in Northern Ireland's deadliest terror strike, a judge ruled Friday. State prosecutors had assembled a sufficiently strong case against Sean Hoey in the Aug. 15, 1998 attack in the town of Omagh, Magistrate Desmond Perry said. Hoey, 36, is the first person to be charged with murder in the bombing.
