Ukrainian forces used two helicopters to attack a fuel depot in Russia on Friday, causing a massive fire, according to a Russian official.

The alleged airstrike occurred in Belgorod, Russia, just 25 miles from the Ukrainian border. Videos on social media reportedly of the attack show helicopters firing missiles toward the ground followed by an explosion. Eight of the 16 fuel tanks at the facility, owned by Russian oil company Rosneft, are on fire, according to Russian media. The alleged attack comes two days after a Ukrainian official told the Washington Examiner that his country has the right to attack targets inside Russian territory.
