Russian operations in Ukraine continue to be largely stalled and plagued by logistical issues, according to an assessment from the US-based Institute for the Study of War.

In its daily sum-up of the campaign, the institute noted that Russian forces did not conduct any offensive operations near Kyiv on Monday, and instead reinforced their defensive positions.

Similarly, Russian forces in north-eastern Ukraine remained stagnant and have been “unable to solve logistics issues”, the institute said.

In Mariupol, on the other hand, the institute believes that Russian forces have made “slow but steady progress”, and have shelled civilian infrastructure. The institute believes the city will fall sometime in the next few weeks.

Additionally, the institute said that Russia has been forced to deploy “low quality” reserves, including “low readiness units” from Russia’s Far East, to replace losses in frontline combat units.
