The government-backed Janjaweed militia, accused of carrying out atrocities in the western region of Darfur in the early 2000s, now have a new role.

They were accused of riding camels and horses into villages seen as sympathetic to rebels, burning them to the ground, killing the men and raping the women.

Now renamed the Rapid Support Forces, they have been tasked with tracking down traffickers and stopping migrants heading to Europe - a role funded by the European Union (EU), although the EU has denied that any money goes to the ex-Janjaweed.

It is not entirely clear why the former fighters have now taken to shaving off afros, but the hairstyles tend to be associated in conservative religious and social circles with people who are "deviant".
