Ammo find: The scene in Wattle Bridge where a suspect device and ammunition were discovered by police
In a statement last week, the CIRA claimed they attempted to draw officers to the location for a gun attack.
Yesterday police continued to comb the area, with the alert expected to drag on into the weekend.
PSNI Chief Superintendent Andy Freeburn thanked the community for their patience over recent days. From speaking with the local community, it is clear that the people responsible for this disruption have no support, he said. Together with partners on both sides of the border we have been working long hours to progress this complex and difficult operation to a safe conclusion. At this stage it is not possible to say when we will complete the search but we anticipate that it will run at least into tomorrow.
