Two explosions were heard on Tuesday afternoon in Zubin Potok, while three more in North Mitrovica - both municipalities inhabited by a majority of Serbs in the northern part of Kosovo. 

According to the reports of some Serbian media, the explosions in Zubin Potok occurred at the time when members of the Municipal Electoral Commission, under the escort of members of the Kosovo Police, entered the premises of the municipal facility. 

Sources said that alarm sirens were heard in North Mitrovica before 15:00. Previously, according to them, members of the Municipal Electoral Commission, in the presence of the Kosovo Police, tried to enter the headquarters of the Electoral Commission in this municipality. 

The Central Election Commission confirmed that the municipal election officials went to their offices in North Mitrovica and Zubin Potok on Tuesday, "in order to exercise their official duties", but that such a thing "has not was possible". 

Without giving more details, they warned that they will hold a meeting "to discuss the situation created in the north of the country". 

The four municipalities in the north - Zubin Potoku, North Mitrovica, Zvecani and Leposaviqi - have been without mayors since early November, when they resigned, as a sign of opposition to a decision by the Government of Kosovo to re-register cars with illegal Serbian license plates in the north. 

The President of Kosovo, Vjosa Osmani, then announced December 18 as the date for holding elections in Zubin Potok, North Mitrovica, Zveçan and Leposaviq. 

Lista Serbe – the largest party of Serbs in Kosovo, which is supported by official Belgrade – opposes these elections. 

-Serbia accuses Kurti 

The Director of the Office for Kosovo in the Government of Serbia, Petar Petkovic, accused the Prime Minister of Kosovo, Albin Kurti, of, as he said, "terror" against the Serbs. 

In a post on Twitter, he published several photos where, as he said, the premises of the Municipal Electoral Commission in North Mitrovica, "destroyed by the special forces" of Kosovo, are visible. 

Through a communique for the media, published earlier, Petkovic said that Kurti's goal is to "violently and with weapons seize the four municipalities in the north" and "install Albanian representatives in them, through illegal and illegitimate elections". 

"Everything was planned and directed by Albin Kurti, while the EU-Western Balkans summit is being held in Tirana", said Petkovic.
