Russian troops are now just 25km away from Ukraine capital city of Kyiv, according to the latest intelligence from the UK's Ministry of Defence.
It comes as Russia stepped up its attack on the neighbouring country, moving into new cities and continuing airstrikes in Kharkiv, Mariupol, Chernihiv and Sumy, and Ukrainian President Volodymyr Zelensky said the mayor of the southern port city of Melitopol had been kidnapped by soldiers.
President Zelensky said Vladimir Putin's men had "transitioned into a new stage of terror" after reports emerged that CCTV footage had captured the mayor being taken away with a bag over his head.
