British intelligence spoke about the increasing isolation of Russian forces around Izyum and the threat to Russia, and estimated the probability of losing Kupyansk. This is stated in the intelligence review of the British Ministry of Defense.

 The British Ministry of Defense reminds us that Ukrainian troops began offensive operations in the south of the Kharkiv region on September 6, 2022, and advanced units with a narrow front advanced up to 50 km into the territory that was previously under Russian control.

 "Russian troops were probably caught off guard. The sector was held by small forces, and Ukrainian units captured or surrounded several towns," the review says.

 "Russian forces around Izyum are likely to become increasingly isolated. Ukrainian units are now threatening Kupyansk; its capture would be a significant blow to Russia, as it is located on the supply routes to the front line in Donbas," British intelligence notes.

 As noted, since Ukrainian operations also continue in Kherson, the Russian defense front is under pressure on both the northern and southern flanks.

 As reported, according to British intelligence, against the backdrop of Ukraine's offensive in the south, Russian commanders faced a dilemma: deploy operational reserves to support their offensive in Donbas or defend against Ukrainian forces in the south.
