Sobolev noted today’s session in PACE would actually be dedicated to Ukraine.

"Today, debates will be held on key issues. In particular, the resolution will be considered on human rights abuses by the Russian-backed gangs "DPR" [Donetsk People's Republic] and "LPR" [Luhansk People's Republic] in the territories beyond control of the Ukrainian authorities," the deputy chairman said.
