A senior Ukrainian military official conceded at a briefing on Thursday that Russia had the upper hand in fighting in Ukraine's eastern Luhansk region at present.
"Russia has the advantage, but we are doing everything we can," General Oleksiy Gromov said.
Gromov also said Ukraine had observed Russia moving Iskander missile systems to Belarus' western Brest region, which Gromov said raised the possibility of new missile strikes on west Ukraine.
