Hargeisa (Arabic: هرجيسا) is the capital of the state Somaliland and the second largest city in Somalia.
These photos are a small side-project from a field mission documenting the work of the Finnish NGO Physicians for Social Responsibility - specifically their long-running effort around TB in Somalia (their site is in Finnish but you can get some of the way with Google Translate - I'll work with them on the rest).
P.S. It is not uncommon for words in Somali to have several different spellings in English [e.g. Hargeysa / Hargaysa].
P.P.S. If you've got appetite for more Africa then do see this collection, or indeed this pre-Flickr effort: photography.ambjorn.com
