Shop owners in Tyrone are being urged by police to check their premises after an incendiary device was found in a supermarket in Strabane early this morning.
A PSNI spokeswoman said bomb disposal experts a defused a "viable device" which was found in the shop on the Branch Road shortly before 3 a.m. A number of items were also removed for forensic examination.
The discovery follows a police warning that business owners in Derry, Coleraine, Strabane and Ballymena should review their security. They have also appealed to the public to be extra vigilant and immediately report anything suspicious to the police.
Dissident republicans were linked to a spate of fire bombings which destroyed several business premises across the North in the run-up to and throughout the Christmas period.
An agricultural supplies store in Strabane was destroyed by an incendiary device last Saturday.
