Africa has the worst rate of road traffic deaths in the world, according to a report by the World Health Organization.

The figures for Africa are 26.6 deaths per 100,000 population - that's nearly three times the rate in Europe.

The report says many African and South American countries do not have sufficient speed limit laws.

But the statistic on vehicle safety gives the most insight into the reason for the higher rate of accidents in Africa.

The countries that do not apply UN vehicle safety standards are marked in red on the graph blow - as you can see, this is almost all of Africa.

These standards require vehicles to have features that can prevent a crash - such as electronic stability control and advance braking.

The number of road traffic deaths continues to rise steadily, the reports.

Botswana, Ivory Coast and Cameroon are countries where death rates have increased.

Egypt, Angola, Burkina Faso and Burudi are among those that have seen a reduction.

Africa also has the highest proportion of pedestrian and cyclist moralities.

In Ghana, almost half of those killed are pedestrians; in Ethiopia, and Kenya this is 37%.

In Kenya, one in four of those killed is in an accident involving two- and three-wheeled vehicles.
