Last week, 200 parents and 300 inhabitants of Dalj, Aljmas and Erdut sent a letter to Education Minister Dragan Primorac, demanding that their children should not be taught by "people who, among other things, are long-standing (Vojislav) Seselj's Radicals".
They also informed Deputy Prime Minister Jadranka Kosor and local authorities.
About 400 children attend the elementary school in Dalj, including 177 who have classes in Serbian.
Principal Zvonko Konjarik said that all ethnic Serb children and only 80 Croats arrived at school today.
He voiced confidence the issue will be settled at tomorrow's meeting with representatives of the education ministry, Osijek-Baranja County, the school and the parents.
