Ukraine’s armed forces are introducing a new facet of air defence, made up of small groups deploying interceptor drones, as the country braces for new mass Russian attacks, Volodymyr Zelenskyy said on Monday. Ukraine is still reeling from a wave of Russian strikes earlier this month that knocked out power and heating to thousands of apartment blocks in freezing temperatures, particularly in the capital, and Zelenskyy has repeatedly called for air defences to be strengthened. “There will be a new approach to the use of air defences by the air force, concerning mobile fire groups, interceptor drones and other ‘short-range’ air defence assets,” the Ukrainian president said in his nightly video address. “The system will be transformed.” Zelenskyy announced the appointment of a new deputy air force commander, Pavlo Yelizarov, to oversee and develop the innovation.

Zelenskyy also warned Ukrainians to be “extremely vigilant” ahead of anticipated new Russian attacks. “Russia has prepared for a strike, a massive strike, and is waiting for the moment to carry it out,” he said, urging every region in the country to “be prepared to respond as quickly as possible and help people”. Zelenskyy and foreign minister Andrii Sybiha both warned at the weekend that Ukrainian intelligence had noted Russia was conducting reconnaissance of specific targets, particularly substations that supply nuclear power plants. Ukrainian energy minister Denys Shmyhal said on Monday that he had informed the head of the International Atomic Energy Agency (IAEA) about Russian preparations for more strikes on Ukrainian energy facilities, including those that ensure the operations of nuclear plants.

The IAEA said on Monday that a back-up power line had been reconnected to Ukraine’s Zaporizhzhia nuclear power plant after repair work carried out under an IAEA-brokered ceasefire. The Ferosplavna-1 line is one of two high-voltage lines supplying electricity to the Russian-controlled plant in Ukraine and was disconnected earlier this month.

Russia launched a barrage of drone strikes on Ukraine’s energy infrastructure overnight to Monday, cutting off power in five regions across the country amid sub-zero temperatures and high demand, Ukrainian officials said. Russian forces had launched 145 drones and air defences shot down 126 of them, the Ukrainian air force said. “As of this morning, consumers in Sumy, Odesa, Dnipropetrovsk, Kharkiv and Chernihiv regions are without power,” the energy ministry said. “Emergency repair work is under way if the security situation allows.”

Ukraine will face enormous challenges to organise its first elections since Russia’s 2022 invasion, with its infrastructure shattered and millions of people displaced by war, the country’s election chief said. Bringing Ukraine’s voter registry up to date and making the proper preparations for a vote would take significant time, Oleh Didenko, the head of Ukraine’s Central Election Commission, told Reuters. Amid diplomatic efforts to end the war, US president Donald Trump has demanded Ukraine hold elections, even though they are banned under martial law – in force since the invasion – and a majority of Ukrainians oppose a wartime ballot.

Vladimir Putin’s special envoy Kirill Dmitriev will travel to Davos in Switzerland this week and hold meetings with members of the US delegation on the sidelines of the World Economic Forum (WEF), Reuters has reported, citing two sources. Ukraine’s top negotiator, Rustem Umerov, said on Sunday that talks with US officials on ending the war would continue at the WEF this week.

Major disturbance in the Earth’s magnetic field may make northern lights visible far more south than usual

The aurora could be visible across Canada and much of the northern tier of US states on Monday night, and possibly even further south, following a major disturbance in the Earth’s magnetic field, a forecast shows.

The forecast, from the National Oceanic and Atmospheric Administration’s space weather prediction center, comes amid intense geomagnetic and solar radiation storms, said Shawn Dahl, service coordinator at the center.
