Soldiers pulled out of Massereene Army barracks
Hundreds of troops have been moved out of the military base where two soldiers were murdered last year.
About 450 engineers were transferred from Massereene Army barracks in Antrim to another camp at Aldergrove.
The move comes amid increased dissident republican acitivity in the area, although the MoD has said the decision was not prompted by security concerns.
Last year Sappers Mark Quinsey (23) and Patrick Azimkar (21) were gunned down as they collected pizza from the gates of the Massereene hours before they deployed to Afghanistan.
Five others were also seriously wounded in the attack that was claimed by the Real IRA.
