The scale and strength of Ukrainian resistance continue to surprise Russia, UK intelligence said, APA reports.

“It has responded by targeting populated areas in multiple locations including Kharkiv, Chernihiv, and Mariupol. This is likely to represent an effort to break Ukrainian morale. Russia has previously used similar tactics in Chechnya in 1999, and Syria in 2016 employing both air and ground-based munitions,” UK intelligence said.

The UK intelligence reported Russian supply lines reportedly continue to be targeted slowing the rate of advance of their ground forces: “There is a realistic possibility that Russia is now attempting to conceal fuel trucks as regular support trucks to minimize losses.”
