Riots broke out in the early hours of Dec. 3 at Greece's frontier with Macedonia as migrants and asylum seekers stranded there for the past two weeks blockaded the border, preventing people from Syria, Iraq and Afghanistan from crossing. Since Nov. 18, only refugees from those three countries have been admitted into Macedonia, while other nationalities have been turned away. Many of those refused entry have boarded buses and returned to Athens in recent days, but about 3,000 have stayed to protest being discriminated against on the basis of nationality. Some have embarked on hunger strikes while several Iranian asylum seekers sewed their lips closed last week. (IRIN)
