Macedonian police say 14 migrants were injured early Sunday when the van they traveled in went off the road after the driver tried to escape a police checkpoint.

Police tried to stop the van for a routine check shortly after midnight, but the driver speeded up. The van went off the road and crashed into an underpass pillar.

The unhurt driver was arrested.

The injured migrants have been taken to hospital in the central Macedonian town of Veles. Two with more serious injuries — hip and leg fractures — were transferred to a hospital in the capital Skopje.

Macedonia has become one of the main transit routes for thousands of migrants from the Middle East and Africa, entering from neighboring Greece on their way to western European countries.
