The headmaster of the Catholic primary school in Antrim, where a viable pipe bomb was discovered by a pupil, says a leading loyalist assured him an attack like this will never happen again.

Eight-year-old Brendan Shannon, from St Comgall's Primary on the Ballymena Road, lifted the pipe bomb and handed it over to one of his teachers on Monday morning.
The P5 boy and his twin sister, Ciara, had arrived early on their bicycles to help deliver milk to classrooms when he noticed the device lying on top of a painted line close to the playground wall.
Brendan was born in Australia, where his parents lived for many years before returning to their native Northern Ireland.
"We came back here thinking it was safe. I spend my time trying to convince people of that and now this happens", Brendan's mother Siobhan Shannon told UTV.
Headmaster Hilary Cush says around 250 pupils and their parents pass the spot where the device was found every day.
"Four-year-olds coming to school for the first day... How could you possibly contemplate - whether they are Catholic or not - how could you possibly contemplate blowing that life to bits? It is not acceptable", Mr Cush told UTV as St Comgall's returned to normal on Tuesday.
The headmaster insists he has received assurances from a leading loyalist that such attack will never happen again.
"I felt that he was the voice of sane loyalism and that he was prepared to come and share time with me in my Catholic school to discuss this matter and reassure me that he felt it was an atrocious act.
"I interpreted that as a possibility that this was a one-off. It was despicable and it won't happen again."
Loyalist splinter group the Real UFF has been blamed for leaving the device in the playground.
After lifting the pipe bomb, Brendan walked into the school and handed it over to one of the teachers, who admits she didn't immediately realise what it was.
"I took the pipe from Brendan and was standing with it in my hand. And then I dismissed the children and said I would sort it out for them", Marie Hannigan told UTV.
"My colleague then said to me, Mrs Hannigan I would put that down if I were you. And I looked at him and I said, why? And he said, put it down now please, can you not see the wire that is coming from the bottom of it? And I then realised and I set it down on the windowsill."
