Russian troops are struggling with supply lines and ebbing morale, according to the latest assessment of the Ukrainian war from British intelligence.

In a Twitter post shared Thursday morning, the ministry of defense explained how the Russians have shifted their lines of attack.

It wrote: Progressing offensive operations in eastern Ukraine is the main focus of Russian military forces.

Russian artillery and air strikes continue along the Donbas line of control.

The Donbas region is in eastern Ukraine, and encapsulates Donetsk and Luhansk areas partially occupied by pro-Russian rebels since the annexation of Crimea back in 2014.

This renewed focus on the east comes after troops withdrew from the Kyiv region leading to the discovery of the Bucha massacre.
