Ukrainian President Volodymyr Zelenskyy has welcomed United States President Donald Trump’s announcement that Russia will not attack Kyiv and “various” Ukrainian towns for seven days as civilians struggle with a lack of heating amid freezing winter temperatures. “De-escalation steps contribute to real progress toward ending the war,” the Ukrainian leader added. Trump said earlier on Thursday that Russian President Vladimir Putin had agreed to his request not to fire on Ukraine’s capital Kyiv for a week due to severely low temperatures. Temperatures are forecast to drop to -23 degrees Celsius (-9.4 degrees Fahrenheit) overnight in the Ukrainian capital this week. Russia’s capital Moscow has experienced its heaviest snowfall in 200 years during the month of January, the meteorological observatory of Lomonosov Moscow State University said on Thursday, according to Russia’s state TASS news agency.
