A hyena stands chained to its handler at a circus in Gabasawa, Kano State, Nigeria, July 27, 2021. Hyenas are often viewed as repulsive and sinister, partly due to their scavenging habits in the wild, but in northern Nigeria some men keep the creatures in their homes, display them at festivals and even use their dung to make remedies.

A combination photo shows some of the colourful doors seen in Rabat's Medina and Kasbah of the Udayas, September 2014. UNESCO made Rabat a World Heritage Site two years ago and media and tour operators call it a “must-see destination”. But it seems the tourist hordes have yet to find out. While visitors are getting squeezed through the better-known sites of Marrakesh and Fez, the old part of Rabat - with its beautiful Medina and Kasbah of the Udayas - remains an almost unspoiled oasis of calm. Smaller and more compact, its labyrinths of streets, passages and dead ends are a treasure trove of shapes and colours, of moments begging to be caught by the photographer's lens.
