Speaking of the arrest of members of UNMIK during the ROSU unit’s operation of May 28, Tanin said that the Kosovo authorities violated a series of international regulations, quoted Serbian media. "The immunity of UN personnel since the arrest was not respected. UN property was illegally confiscated and searched despite all relevant international laws and immunities, "said the head of UNMIK. According to him, the Kosovo authorities provided information that "does not correspond to reality" and finally, a member of UNMIK was declared persona non grata. "The doctrine of undesirable persons does not apply to UN staff," Tanin said.
