Serbian President Aleksandar Vučić has warned the Western Balkan country faces a major crisis as its largest oil refinery prepares to shut down unless US sanctions authorities approve an operating license by Thursday.
The Petroleum Industry of Serbia (NIS) refinery is currently operating in "warm circulation" — a reduced-capacity mode — and has four days until complete shutdown unless approval comes from the US Office of Foreign Assets Control, Vučić said in an address to the nation.
