The Queen has paid tribute to the "fortitude, dignity and indomitable spirit" of the people of Aberfan, on the 50th anniversary of the disaster which cost the lives of 116 children and 28 adults.
On 21 October 1966, 150,000 tonnes of coal waste slid down a hillside in the small mining village, engulfing a junior school and neighbouring houses.
Residents of Aberfan have attended a day of commemorative events, including a memorial service at the cemetery.
The Prince of Wales also visited the village, where he delivered a speech - including a message from the Queen.
The message read: "As you come together as a community today to mark 50 years since the dreadful events of Friday 21st October 1966, I want you to know that you are in my own and my family's thoughts, as well as the thoughts of the nation."
