A third shooting death in three days in Northern Ireland is raising concern that a decade-old peace accord could come unglued, returning the country to the "Troubles."

The incident in the County Armagh town of Craigavon, 28 miles from Belfast, follows the killing of two British Army soldiers over the weekend by another shadowy dissident group, the Real IRA (RIRA), at an Army base also in County Antrim.

Cengiz Azimkar and Mark Quinsey, the two soldiers killed in the attack at Massereene barracks, were due to be deployed to Afghanistan. The killings marked the first attack on British forces since 1997.
Irish officials are calling for help – and for peace.
