Demonstrators carried the Hungarian flag together with the Szekler flag, which has become known as a symbol of the Hungarian minority who are looking for more independence in Romania.
Protesters are calling for territorial autonomy, stating that their request will not interfere with Romania’s sovereignty.
Romania is home to an estimated 1.2 million of ethnic Hungarians, many of whom took to the streets on Saturday, marking the Day of Freedom of the Szekely.
