Nearly 150 Yazidi migrants from Sinjar (Shingal) in northern Iraq are stranded outside refugee camps in Serres, Greece, having been refused entry by the country's authorities.

Until recently, there were dozens of camps housing such asylum seekers in Greece, but authorities have been shutting them down following protests from local communities. IMAGES AND SOUNDBITES
