Russia-Ukraine war live: drone combat intensifies; Russia suffers cross-border attack

  • Ukraine and Russia launched a swarm of drones at each other’s territories on Sunday as both sides step up attacks, with the Russian assault reportedly killing one person in Odesa and the Ukrainian strike targeting a Russian military airfield.

  • Ukraine’s air force said on Sunday morning that it had destroyed 20 drones and a cruise missile that Russia launched overnight. Nine of the drones were downed over the southern Odesa region, with falling debris starting a fire in a residential house and killing one person.

  • The Russian defence ministry said in a social media statement that its air defence systems destroyed or intercepted a total of 35 Ukraine-launched drones over Lipetsk, Volgograd and Rostov regions. It did not say what was targeted or whether there was any damage.

  • The Freedom of Russia Legion, a Ukrainian-based paramilitary group of Russians who oppose President Vladimir Putin, claimed responsibility on Sunday for a cross-border attack a few kilometres into Russia’s Belgorod region. The group, designated as terrorist in Russia, said it had destroyed a platoon stronghold of Russian troops near Trebreno village, without specifying whether it had destroyed infrastructure or killed soldiers, and said it had left mines behind.

  • Ukraine’s security services said Sunday they had discovered a bug in one of the offices used by army chief Valery Zaluzhny, but added that it was “not operational”.

  • The Russian president, Vladimir Putin, vowed to make Russia a “sovereign, self-sufficient” power in the face of the west. In a campaign speech he accused the west of unsuccessfully trying to “sow internal troubles” in Russia.

  • Putin also warned of “problems” with neighbouring Finland after it joined Nato earlier this year. Russia plans to reorganise military divisions to station more troops in its north-west region, by the EU and Nato border.

  • Putin dismissed claims from the US president, Joe Biden, that Russia could attack a Nato country as “nonsense”. It came after Biden said Putin would not stop at Ukraine if it secures victory, as he pleaded with Republican lawmakers to authorise further aid to Kyiv.

  • Visit of Ukraine’s president, Volodymyr Zelenskiy, to Washington DC last week has yet to bear fruit as Biden called lack of congressional support for aid a “Christmas gift” to Russia. Biden has requested $61.4bn (£48.4bn) in further aid to Ukraine but Republicans in Congress have rejected the proposals.

  • But one top Democrat said he was “very optimistic” about a resolution. US congressional negotiators worked deep into the weekend in an attempt to craft an urgent deal linking aid to Ukraine and Israel to new border security. “I’m very encouraged,” said senator Joe Manchin.

  • Russia is not interested in extending the Black Sea grain deal, the agriculture minister said. The deal led to 33m tonnes of grain leave Ukraine’s ports before it collapsed in July.

  • Ukraine claims Russia has suffered almost 350,000 troops dying or being injured. The figure is higher than the 315,000 estimated by US intelligence, according to reports, but even that represents a significant toll for Moscow.

  • Ukraine continued its use of “memetic warfare” as the defence ministry posted a video of two Russian tanks being destroyed, with guitar music and the caption “WELCOME TO UKRAINE”. Scholars have tracked the use of memes to try and grab control of the war narrative.

  • An intelligence report from the UK Ministry of Defence said Russia is likely to deploy “electoral fraud and voter intimidation” when elections take place in occupied Ukrainian territories. Donetsk, Luhansk, Kherson and Zaporizhzhia will vote in March’s presidential elections but they are expected to not be “free or fair”.

  • It comes as Putin was confirmed to be running for president again as an independent candidate in Russia after two decades in power. Russian news agencies reported the news on Saturday, with the victory of Putin, 71, a formality.

  • Russian rocket forces have loaded a new Yars intercontinental ballistic missile into a silo at the Kozelsk base south-west of Moscow. The missiles are capable of delivering multiple nuclear warheads.

  • More than a year after the Russians retreated from Izium, the Ukrainian city is wracked by suspicion and distrust about collaborators. Read Shaun Walker’s Observer dispatch from a city still in ruins here.

  • Lorry blockades are continuing at the Polish-Ukrainian border. Polish drivers say Ukraine is undercutting them as about 2,150 Ukrainian lorries remain stuck in Poland unable to return.
