Governor Peter Kaiser has asked for the "harshest consequence" following the attack.
He said: "This unbelievable atrocity must have the harshest consequences! I have always said very clearly and unequivocally: anyone who lives in Carinthia, in Austria, must respect the law and must adapt to our rules and values.
"Anyone who violates these rules must face the harshest consequences - they must be put on trial, imprisoned and deported!"
Rainer Dionisio, head of public relations at the Carinthian State Police said: "This is an extraordinary act. Something like this is unprecedented in Carinthia The background to the act is still unknown, and the entire environment is now being investigated."
