A pipe bomb has been found yards from a school playground in west Belfast.
A number of residents in the Cavanmore Gardens area were evacuated when the viable device was discovered this morning. It was left close to De La Salle college secondary school.
Elsewhere, another viable explosive device was found in the Alexandra Avenue area of Armagh, prompting an evacuation of nearby residents.
West Belfast MP Paul Maskey condemned the perpetrators of the incident in his constituency.
"Those who left a viable explosive device yards from La Salle secondary school and a playground need to come forward and explain to this community why they have put local residents and school children in danger," he said.
"Many residents had to leave their homes in near freezing conditions while this device was dealt with. Those responsible have no support in this area yet continue sporadically to endanger the community. They are not wanted and these actions are futile yet highly reckless.
"It is only a matter of time before one of these devices explode and injures or indeed kills a local person. It is my belief that those behind such actions will hide from this community as they have done every time they choose to endanger and inconvenience local residents."
West Belfast Assembly member Alex Attwood said those responsible had done nothing but bring disruption and misery to the community.
"People want to get to work, do their shopping and get to school, without fear or inconvenience," said the SDLP representative.
Army technical officers have taken both devices away for further examination. Roads have been reopened and residents allowed to return to their homes.
