Romania's foreign minister says he will summon the Hungarian ambassador to express his discontent after the flag of a group seeking autonomy within his country was draped over Romania's national emblem at its embassy in Budapest.

Teodor Melescanu on Monday called on Hungarian authorities to "guarantee the inviolability and integrity of Romanian missions and their staff."

The incident came days after Romanian Prime Minister Mihai Tudose angered Hungarians with provocative comments about autonomy efforts by Szeklers, an ethnic Hungarian group who live in Romania.

Tudose said that "if the Szekler flag flies on institutions" in Romania "they'll all fly next to the flag." In Hungary, the comments were taken to mean that they should be hanged.

Hungarian Foreign Minister Peter Szijjarto called the Romanian premier's comments "totally unacceptable and unworthy of Europe, European values and the 21st century."
