While some 7,500 Russian soldiers remain on the territory of Donetsk and Luhansk oblasts, Kremlin-backed separatists have been expanding their activities to western and central part of the country, Ukraine’s security service (SBU) said on Nov. 26.

“The geography of crimes and sabotage has expanded significantly. It now includes not only east but also west,” Markian Lubkivsky, an adviser to SBU head Valentyn Nalyvaichenko said at the briefing.
