Belgrade - Serbia plans to raise the question of the responsibility both of Ukraine and Russia for the crippling gas crisis, the head of national supplier Srbijagas, Dusan Bajatovic, said Thursday.
"We will ask for explanations from the Russian Jugorosgas and Gazprom, as well as the Ukrainian Naftogaz and if we find any of them unacceptable, we will raise the question of responsibility," Bajatovic told radio B92.
Jugorosgas is a majority Russian joint venture with Serbian partners with the monopoly right to supply Russian gas.
A lawsuit against Ukraine was already being prepared in Serbia, Bajatovic said. He said there was no "legal and economic ground" for proceedings against Russia.
