Surge of refugees puts strain on Iraqi town

Almost half a million Iraqis have fled their homes in the province of Anbar after a military operation against an armed group. Most have arrived north of Baghdad in a town where residents are already struggling to cope. Samarra has a population of 300,000 people, and the almost 200,000 people from Anbar is clearly putting a strain on the town. Al Jazeera's Imran Khan reports from Samarra.
