A new fence of the 'Svetozar Markovic' primary school in Serbia's southern city of Leskovac was sprayed with Nazi symbols of SS Division 'Prince Eugen', swastika and the Celt cross.
Leskovac's 'Rosa' NGO told the Beta news agency it would request an urgent reaction and the arrest of the perpetrators.
"We condemn any form of Fascism and remain deeply upset with such graffiti that appeared in Leskovac for the first time," 'Rosa's president Zoran Saitovic said.
The symbols were sprayed next to the place where the youths usually gather in the evenings.
The police in the city told Beta they launched a probe and were looking for the perpetrators.
