A letter bomb has been discovered at a postal sorting office near Belfast.

The alarm was raised when staff at the mail centre in Newtonabbey became suspicious about the contents of a letter.
British army bomb experts and the PSNI were called to the scene. Army bomb experts described it as a "viable device".

Dissident republicans are suspected of involvement.

Meanwhile, the PSNI is appealing for witnesses after a petrol bomb attack in County Antrim.

It happened at premises on the Diamond in Rathcoole in the early hours of this morning.
