“Before fleeing from Kherson, the occupiers destroyed all the critical infrastructure: communications, water, heat, electricity,” Zelenskyy stated in a video address on Saturday.“It’s a big moment and it’s due to the incredible tenacity and skill of the Ukrainians, backed by the relentless and united support of the United States and our allies,” US National Security Adviser Jake Sullivan said while travelling to Cambodia with President Joe Biden for a regional summit.Sergey Markov, a former adviser to Russian President Vladimir Putin, told Al Jazeera that losing Kherson was a blow for Russia, but that Moscow’s mobilisation means it will be Ukraine’s last victory.But now that privilege will be over for Ukrainian army, because 300,000 mobilised Russians will come to the Russian army.”The Kremlin meanwhile insisted Kherson was still part of Russia and it did not regret annexing the entire Kherson region.Russia announced the annexation of four Ukrainian regions, including Kherson, in September — a step dubbed illegal by Kyiv and denounced by Western countries."
