The RUC said the incident could easily have resulted in a mass-murder atrocity.
The bungled attack ends a seven-day lull in IRA violence following the murder of an RUC reserve constable who died three days after he was shot in Newry, Co Down, last Sunday.
The RUC has launched an investigation into the shooting of a woman driver, aged in her forties, by a soldier at a checkpoint near Omagh in Co Tyrone yesterday. She was said to be travelling with a child. Last night, her condition in hospital was described as 'ill but
