Britain's worst ever mining disaster has been remembered a century after 439 miners and one rescuer lost their lives in an explosion at Senghenydd in South Wales.

A new monument has been unveiled on the site of the old mine and a memorial garden opened to remember more than 5,000 miners killed in accidents across Wales since the 18th century.
