Somalia, on the north east coast of Africa, is perhaps the ultimate 'failed state'.
Civil wars, fuelled by outside intervention, have been raging almost constantly for the past 20 years - and during most of that time there hasn't been a functioning central government.
It is one of the most dangerous places in the world, with killings, kidnappings and piracy off the coast all rife.
The BBC's Mark Doyle has had rare access to the capital Mogadishu, the epicentre of the violence.

Mark Doyle travelled to Mombasa, Kenya to join a UN World Food Programme ship being loaded up before leaving for Mogadishu. Some three million Somalis currently require aid.
He also spent time on a Canadian naval vessel which accompanies the food aid ship on its journey, in an attempt to prevent attacks of piracy.
