The bitter war between Armenia and Azerbaijan in the Caucasian region of Nagorno Karabakh may have come to an end, but the business of fighting may continue for at least some of its combatants. There’s growing evidence that hundreds of soldiers in this war were mercenaries recruited from mostly rebel-held regions in northern Syria - even though that's strongly denied by Azerbaijan. In this week’s Crossing Continents Ed Butler hears testimony from a number of young Syrians, who say they fought in a war which in most cases they didn't realise they were signing up for. Some speak of shame at having to work this way – a symptom of the increasing economic desperation that's affecting the embattled regions of northern Syria where they live.
