Kryviy Rih, Ukraine — Russia accused Ukrainian forces of staging a daring air raid against an oil depot inside Russian territory Friday morning.
The regional governor said two Ukrainian helicopters attacked the fuel facility in Belgorod, about 20 miles inside Russia, and video showed storage tanks in flames.
A U.S. official confirmed to CBS News senior national security correspondent David Martin that Ukrainian helicopters did carry out the strike, and anther one a couple days earlier against an ammunition depot in the same area.
The official told Martin there was concern in Washington about how Russia might react to the strikes.
Ukrainian officials did not claim responsibility for the attack themselves, but as CBS News senior foreign correspondent Holly Williams reports, it was a significant move by Ukraine's forces.
A video screengrab shows firefighters responding to a fire that broke out at a fuel depot in Belgorod, Russia, which the regional governor blamed on an attack by Ukrainian military helicopters on April 1, 2022.
Just west of Zaporizhzhia, CBS News senior foreign correspondent Holly Williams met some of the Ukrainian forces who stood in their way. »
