The people of Aberfan in south Wales are having to relive the terrible events of half a century ago when a mountain of coal waste collapsed onto the village school claiming the lives of 116 children and 28 adults.
The scale of the disaster made headlines around the world, and people gave generously to support the shattered community.
But as Huw Edwards reports, the families of Aberfan had to fight for decades for justice.
