Calls for further investigations into tragedy in south Wales that killed four men in September 2011
Bereaved families and survivors of a south Wales mining tragedy in which four men died exactly 10 years ago are calling for further investigations into the disaster.
Relatives say they still do not have the answers to why their loved ones were killed at Gleision colliery on 15 September 2011, one of the UK’s worst mining disasters in recent years.
