Police are seeking the three suspects who disappeared after Wednesday's shootings, which occurred during a confrontation with some 200 Bangladeshi farm workers in the country's rural south who say they have not been paid for half a year.
Political parties and trade unions expressed shock, and about 100 people took part in a protest by labor groups outside the Labor Ministry in Athens.
The economic pain, coupled with waves of illegal immigration in recent years, has fuelled a rise in anti-immigrant sentiment that swept members of an extreme far-right party into Parliament last year.
The Greek section of the Doctors of the World medical aid group said the shootings should be treated as a case of racist violence, which carries more severe penalties.
"The protracted financial crisis, combined with a constantly growing mood of xenophobia and tolerance for racist violence, is leading to incidents of barbarity and brutality that ... insult Greece," a group statement said.
