Greek police say that they have arrested three foreman for the shooting of 28 Bangladeshi farm workers who were demanding unpaid wages. The men shot at a crowd of 200 workers. The region where the workers were shot has had problems before, with thousands of migrant workers living in the area picking crops. Workers went on strike in 2008 over poor working conditions.
