Ai Weiwei Films in Gaza for Refugee Documentary

Chinese artist and dissident Ai Weiwei has begun interviewing refugees in Gaza for his documentary on the world refugee crisis. A new report says a record number of people - nearly 41 million - are internally displaced as a result of conflict or natural disaster. As part of his project, Ai has been visiting migrants in Europe and in the Middle East, staging events to draw attention to their plight. Zlatica Hoke reports.
