Relatives of the victims of the Six Bells mining disaster are remembering their loved ones on the sixtieth anniversary of the tragedy.
On June 28 1960, an explosion tore through underground workings at Six Bells Colliery in Abertillery, killing 45 men.

Hazel Crandon can picture the day vividly. Her father-in-law and brother-in-law both worked at Six Bells.
When news of the explosion broke, she rushed to her mother-in-law's house.
My mother in law who was totally deaf. And she couldn't understand what had happened. But there was a terrible gloom throughout the whole of the valley.
Thomas George Crandon, 46, had been carrying out repair work underground.
At 10:45am, a ignition of gases caused an explosion in the district of the mine he and 48 others were working in.
Only three of the men survived.
You just can't realise what had happened, and the tremendous effect it had on people. And then all the funerals. 100s of people... they came from everywhere.
19-year old Dennis Lane was one of the youngest victims.
His cousin Pat, who was away training as a nurse, returned home to Abertillery on hearing the news.
Sixty years on, Pat remembers her cousin with great fondness.
We lived just a few doors away from one another, and we were brought up as twins.
Dennis's body was the first to be recovered.
A definitive cause for the explosion was never established, although a spark from a falling rock was thought to have been highly likely.
Six Bells Colliery returned to production following the disaster. It later merged with Marine Colliery in Cwm, before closing in 1988.
The colliery buildings were soon demolished, leaving little sign of the site's previous purpose, or indeed anything to represent the tragedy of 1960.
A small memorial to the disaster was erected in Six Bells in 1995.
2010 saw a major development for the 50th anniversary of the disaster - the construction of a 20 metre high steel statue.
Designed by Sebastian Boyesen, the Guardian stands on the Six Bells site itself, inscribed with the names of the 45 men who died.
I didn't want to go in the beginning. I just didn't want to see his name on there.
This year, lockdown restrictions mean the annual service at St John's Church isn't able to happen.
But the anniversary won't be forgotten.
Prayers will be said at the Guardian. Local schoolchildren have been learning about the disaster in recent weeks. And thousands of people have now visited the site, learning of a tragedy that's still remembered across the valley.
