On 25 March 1975, Saudi Arabia’s King Faisal was murdered, shot by his nephew as he bent to kiss him as a greeting.
The king’s oil minister Ahmed Zaki Yamani was standing beside him when the gun went off.
In 2017, Ahmed’s daughter, Dr Mai Yamani, told Louise Hidalgo of her father’s pain at witnessing the death.
