The drone was allegedly surveilling Crimean troop positions over the Turetsky Val block-post, the Novosti Kryma (News of Crimea) online newspaper reported.
The unsanctioned aircraft had been spotted by Crimean self-defense forces and Berkut policemen.
Another, heavier drone, a two-engine one, has been allegedly shot down and fell outside the block-post’s area.
Each drone costs around $4 million.
