The 69-year-old father was travelling from Dakar, Senegal’s capital, to neighbouring Mauritania with four of his children for Eid al-Fitr, his eldest son at the wheel. But about 90 km outside the capital, his son suddenly lost control of the vehicle, crashing into a tree. “I blacked out,” Dieng recalls, “and woke up in the hospital.” When he inquired about his four children, he received tragic news: they had all been killed on impact. “It’s been 10 years,” he says. “But it feels like yesterday.”
