Ffos-y-Fran protesters: 'We're here to shut down the mine'
Climate activists have set up camp alongside the UK's largest opencast mine in Merthyr Tydfil.
Campaign group Reclaim the Power say they will attempt to halt operations at the Ffos-y-Fran site on Tuesday, two days before the assembly election.
Protesters want a moratorium -a suspension - on Welsh opencast mining.
Miller Argent, the company which runs Ffos-y-Fran, said it supports 230 local jobs and affordable electricity generation across the UK.
Kara Moses, from Reclaim the Power, told BBC Wales they planned to "shut down the mine".
