Domhnach Na Fola is Gaelic for “Bloody Sunday’.  Domhnach Na Fola took place on this date in 1972, when British Paratroopers opened fire on a peaceful civil rights parade in Northern Ireland killing 14 and wounding 14 more.  Some of those demonstrators were shot in the back while fleeing.  Others were gunned down while trying to assist the wounded.

A few years later, Bono wrote a song about the event called “Sunday, Bloody Sunday”.
