(Reuters) - Ukrainian troops said they had retaken the key bastion of Lyman in occupied eastern Ukraine, a stinging defeat that prompted a close ally of Russian President Vladimir Putin to call for the possible use of low-grade nuclear weapons.
LYMAN
* Russia said its troops had withdrawn from Lyman to avoid being surrounded by Ukraine's army.
* Ramzan Kadyrov, a Putin ally and head of Russia's Chechnya region, said Moscow should consider using a low-yield nuclear weapon in Ukraine after the loss of Lyman.
* U.S. Defense Secretary Lloyd Austin cheered Lyman's recapture, saying it was an encouraging battlefield success and that the loss of the logistics and transport hub will pose a dilemma for Russia's military.
* The "liberation" of Lyman in the Donetsk region is a key factor for "further de-occupation" in the neighbouring Luhansk region, said its governor, Serhiy Gaidai.
ZAPORIZHZHIA
* A Russian patrol detained the director general of Ukraine's Russian-occupied Zaporizhzhia nuclear power plant, the state-owned company in charge of the plant said. The United Nations nuclear watchdog said Russia had confirmed the move.
* International Atomic Energy Agency chief Rafael Grossi is expected to hold talks in Moscow and Kyiv in coming days on the creation of a protection zone around the Russian-held Zaporizhzhia plant, the U.N. watchdog said.
CASUALTIES
* Ukraine's SBU security service said at least 20 civilians were killed in Russian shelling of a civilian convoy in late September in an eastern "grey zone" between Russian- and Ukrainian-controlled territory.
GAS FLOWS
* Italy's Eni said it would not receive any of the gas it had requested from Russia's Gazprom (MCX:GAZP) for delivery on Saturday, but the firms said they were working to fix this.
* Greece and Bulgaria started commercial operation of a long-delayed gas pipeline that will help decrease southeast Europe's dependence on Russian gas and boost energy security.
* Russia's Gazprom cut natural gas supplies to Moldova on Saturday by around 30%, said the director of gas firm Moldovagaz, Vadim Ceban.
DIPLOMACY
* Russia failed to win enough votes for re-election to the U.N. aviation agency's governing council, in a boost for Western powers that wanted to hold Moscow accountable following its invasion of Ukraine.
* Germany will deliver the first of four advanced IRIS-T air defence systems to Ukraine in the coming days to help ward off drone attacks, Defence Minister Christine Lambrecht said during an unannounced visit to Odesa.
