The most dangerous place in the world to travel on roads is in the impoverished East African state of Eritrea, says the World Health Organisation (WHO) in its first report on global road safety.

To identify the most hazardous roads, WHO experts sifted through a mass of data which showed that around 1.3 million people are killed each year on the world's highways. A further 20 to 50 million people sustain non-fatal injuries.
