[1] Four separate movements claimed responsibility for the bombings: Mudiad Amddiffyn Cymru ("movement to defend Wales"), Cadwyr Cymru ("keepers of Wales"), Meibion Glyndŵr, and the Welsh Army for the Workers Republic (WAWR), whose attacks were on political targets in the early 1980s.
[citation needed] Letters claiming responsibility for attacks were signed "Rhys Gethin", in homage to one of Owain Glyndŵr's most prominent followers.
