A Russian regional official says that two Ukrainian military helicopters struck a fuel depot on April 1 in the Russian city of Belgorod, located some 25 kilometers from the border with Ukraine.
Regional governor Vyacheslav Gladkov said on the Telegram messaging app that the helicopters struck the facility after crossing the border at low altitude. Gladkov said that two workers were injured in the purported attack.
However, Russian oil firm Rosneft, which owns the fuel depot, said in a separate statement that no one was hurt in the fire. It gave no information on the cause of the blaze.
Unverified video images of the purported attack posted online showed what looked like several missiles being fired from low altitude, followed by an explosion.
Ukraine's defense ministry could not immediately be reached for comment.
