Aberfan disaster: The moment my school was engulfed

Wales has fallen silent as the country remembered the Aberfan disaster 50 years ago.

On 21 October 1966, a mountain of coal waste slid down into a school and houses in the Welsh village, killing 144 people, including 116 children.

The programme heard from a woman who described the moment her school was engulfed and the survivor's guilt she suffered afterwards, and we spoke to a man who volunteered after the disaster and had never previously met a survivor.
