"Human river" of Syrians streams into northern Iraq, says UN refugee agencyListen /
About 20,000 Syrians have streamed into northern Iraq in the last few days, according to the UN refugee agency (UNHCR).
The agency says this is one of the biggest crossings of refugees into a neighbouring country during the Syrian crisis.
Many of the refugees are telling UNHCR that they are fleeing fighting involving various armed groups and increasing tension in northern Syria.
UN Radio's Patrick Maigua discusses this humanitarian crisis in Syria with UNHCR spokesman in Geneva, Adrian Edwards.
