There were a whole bunch of people killed when a bomb exploded prematurely in a customs post in Killeen, Co. Armagh in the 1970s.
I remember that well because I was pen pal (there’s one for the teenagers lol ) with a girl from Dundalk then and she knew one of the RA men who lost their lives in it....a fellow named Oliver Rowntree.
THE family of a lorry driver killed in an IRA bombing in 1972 have said they fear Brexit could spark violence along the border.

As a boy, in the 60s before the balloon went up in 1969, I would spend a few weeks in Belfast every summer in the school holiers.
My granny brought me over and nearly every year we had an train excursion to Dublin with her sisters and a bunch of their grandchildren.
(Or to Drogheda a time or two to see Oliver Plunkett’s head

)
That train stopped at Portadown and customs officers from 6 of 9 came on and did spot checks.
The train then stopped at Dundalk, Co. Louth when customs men from 26 of 32 dis the same thing
No customs since 1923....my Aunt Fanny
