- Summary- Russia pulls out as Ukraine bids to retake city- Kherson is still part of Russia, Kremlin says- Antonivskiy bridge apparently blown up -Russian bloggersLONDON, Nov 11 (Reuters) - Russia's military said on Friday it had completed its withdrawal from Kherson, a lightning-fast retreat of tens of thousands of troops across the Dnipro river in the south of Ukraine.Reuters could not immediately verify the status of the retreat but if true, the speed of the move, involving up to 30,000 men, would be significantly faster than either the United States or Ukraine expected.BRIDGE 'BLOWN'Abandoning an occupied Ukrainian city that was founded by Empress Catherine the Great in the 18th century amounts to a humiliating defeat for Russia after years of touting its post-Soviet military clout.Both the choreography and tone of the retreat, though, contrasted sharply with the much more chaotic defeats of the Russian army in Ukraine's northeast Kharkiv region in September, six months into Russia's invasion of its neighbour.Russian state television showed what it said was the Antonivskiy bridge, the only nearby road crossing from Kherson to the Russian-controlled eastern bank of the Dnipro River."
