The PSNI are investigating a claim that explosive devices have been planted at several locations in Co Armagh.
A coded warning was received by Portadown police indicating that devices had been planted at several road junctions including the M1 and on the Dublin - Belfast rail line.
The main Middletown to Armagh road has been closed until further notice to facilitate searches but no other roads have been closed. The public have been warned not to touch any suspicious objects.
The railway line between Scarva and Portadown has now reopened after being closed this morning as searches were carried out.
