A number of families were evacuated from their homes after a bomb detonated outside a house in County Armagh last night.
Police were called to the Enniskeen area of Craigavon just before 11:30pm.
The army bomb disposal unit was called in and a second viable device was found.
No one was injured in the incident.
The evacuated families were allowed to return this morning and a police investigation is underway.
DUP MLA Carla Lockhart has condemned the incident.
“I would utterly condemn those who left these devices in Enniskeen,” she said.
“It doesn’t matter what cause or reason they think they are advancing; violence is not the way to do it.
“I am concerned at this worrying trend of criminal activity.
“These devices were viable and could very well have caused serious injury or indeed death.”
The PSNI is urging anyone with information to come forward.
