According to a Ukrainian government report, Ukraine was behind three explosions rocked Russian military facilities in the annexed Crimea this past week, including an explosion at a Russian air base, reports CNN.
The official requested anonymity because they were not authorized to share information on this issue with the media.
The report describes the Saki airbase, which was rocked by explosions last Tuesday, as a hard but one time loss for Russian military infrastructure in the peninsula, with subsequent attacks as proof of Ukraine's systematic military capability in targeting Crimea.
After explosions Russia claimed it was a result of an accident and Ukrainian officials have so far declined to confirm on the record that they were responsible.
