Roma women dance as thousands of Roma from all over Romania, which has Europe's largest Roma community, gather to celebrate the birthday of St. Mary and to make wedding arrangements for their sons and daughters in Costesti, 210 km (128 miles) west of Bucharest, September 8, 2010. The European Commission has asked France for evidence that its controversial campaign to send thousands of Roma back to Romania and Bulgaria was in line with EU rules on the free movement of people and discrimination.
