Meibion Glyndwr: Wales' decade of fire bomb attacks
The UK government's attempts to respond to arson attacks on holiday homes in Wales in the 1980s and 1990s have been revealed for the first time.
Papers obtained by BBC Radio Cymru's Manylu programme highlight concerns about sympathy for the arsonists within Welsh-speaking communities.
Only one person was found guilty of being involved in the attacks.
In just over 10 years, a group calling themselves Meibion Glyndwr led a fire bombing arson campaign in Wales.
