US President Joe Biden has signed a proclamation establishing a national monument honouring Emmett Till – the black teenager who was killed in 1955 after he was accused of whistling at a white woman in Mississippi – and his mother, Mamie Till-Mobley.

It marked the fulfilment of a promise Till’s relatives made after his death 68 years ago.
