Sudanese migrant Abdul Haroun leaves Elmley prison in southern England, Britain, January 4, 2016. A Sudanese man who made global headlines in August when he walked 50 km (30 miles) through the Channel Tunnel from France to England, highlighting the plight of migrants, has been granted asylum in Britain. The case of Abdul Haroun, who has been in prison since he was arrested at the English end of the tunnel on Aug. 4, is one of the most dramatic examples of a country struggling to tackle an influx of refugees largely from war zones such as Syria.
