- Summary- Chechen leader Kadyrov scolds top generals- Prigozhin: top brass should fight on front- Russian state television subduedLONDON, Oct 3 (Reuters) - The withdrawal of Russian forces from a strategically important town in eastern Ukraine has prompted two powerful allies of President Vladimir Putin to do something rare in modern Russia: publicly ridicule the war machine's top brass.Russia's loss of the bastion of Lyman, which puts western parts of Luhansk region under threat, touched a nerve for Ramzan Kadyrov, the leader of the southern Russian republic of Chechnya.Kadyrov, who has been close to Putin since his father and former president of Chechnya, Akhmad, was killed in a 2004 bomb attack in Grozny that also killed a Reuters photographer, suggested that Russia should consider using a small tactical nuclear weapon in Ukraine in response to the loss.In a fresh setback for Moscow on Monday, a Russian-installed official confirmed Ukrainian advances along the west bank of the Dnipro River in Kherson region in southern Ukraine, one of four regions Putin claimed last week to have annexed.Asked about Kadyrov's remarks, the powerful founder of the Wagner Group of mercenaries, Yevgeny Prigozhin, congratulated the Chechen leader."
