Dmytro Pletenchuk said on Facebook that the Russians used the offshore gas platform for GPS spoofing to make civilian navigation dangerous.
He posted a video taken at night showing an explosion on an offshore platform and the ensuing fire.
He said that a half a day before the attack, Russian forces had stationed equipment and military personnel on the platform.
The development came after the Ukrainian forces launched a large-scale incursion into the Russia's Kursk border region earlier this week.
