Ukrainska Pravda reports about it.
Head of the SSU Valentyn Nalyvaichenko demonstrated several satellite images.
In particular, the image demonstrate traces of the rockets fired by Grad systems. Russian armed forces installed them 1-2 km inside the Ukrainian territory and after the attacks returned them to Russia.
Also, according to the pictures provided by Nalyvaichenko, vehicles of technical intelligence were invading the territory of Ukraine from Russia. They were close to the border to coordinate further directions of Russian equipment and terrorists to cities and towns of the Luhansk and Donetsk regions.
Also pictures prove what has been known long ago about the movement of Russian military equipment and groups of saboteurs on the Ukrainian territory.
