Ukrainian President Volodymyr Zelenskyy declined to comment on whether he ordered an attack on a Russian fuel depot.
In an interview with FOX News, Zelenskyy said he does not discuss any orders he issues as commander in chief.
Earlier, the secretary of Ukraine’s national security council denied allegations from Moscow that two Ukrainian helicopter gunships had struck the facility in the city of Belgorod north of the border at around dawn Friday.
The regional governor in Belgorod said two workers at the depot were injured, but Russian media cited a statement from state oil company Rosneft that denied anyone was hurt.
But if Moscow’s claim is confirmed, it would be the war’s first known attack in which Ukrainian aircraft penetrated Russian airspace.
