Ukraine war pulls in foreign fighters

French, Spanish, Swedish or Serb, the foreigners fighting for both sides in east Ukraine's bloody conflict hail from across Europe and come with a bewildering array of agendas.

The non-mercenaries among them are motivated by causes which can stretch back to the wars in the former Yugoslavia - and even further still, to the Spanish Civil War of the 1930s.
Russia is the elephant in the room, dwarfing any other foreign nationality, although it is increasingly hard to disentangle Russians fighting as volunteers from regular soldiers allegedly deployed on covert missions.
Ukraine's pro-Russian rebels like to talk up their foreign volunteer fighters, presenting them as latter-day International Brigades fighting "fascism". Meanwhile there has been some debate in Kiev on the wisdom of creating a Ukrainian "Foreign Legion".
Here we look at some of the foreign fighters by country of origin, in a phenomenon which, in a small way, mirrors that of young Muslims from Britain and other parts of Europe travelling to the Middle East to fight in its wars.
