Russian forces have been steadily increasing the intensity of their offensive activity across the front in Ukraine over the past two weeks, the British Ministry of Defense said in its latest intelligence update.

"A key enabler for this is highly likely the freezing ground conditions, which allows cross-country movement of armored vehicles," the update said.

The Ukrainian General Staff reported on January 19 that Russian attacks on the front line had increased by 27% compared to the previous day, according to the British ministry.

Additional data from the Ukrainian General Staff comparing the period of January 14-18 with the previous five-day period supports this increase in Russian assaults, the update said.
