Ukraine is now living through its most difficult winter in recent memory.
With January temperatures plummeting below -15C, Russia has been attacking energy infrastructure, leaving about a million Ukrainians without heating.
The capital, Kyiv, is the main target of such attacks. Following the latest Russian bombardment overnight into 24 January, almost 6,000 apartment blocks were left without heating, according to mayor Vitaly Klitschko.
This is the third such Russian attack targeting Kyiv's heating infrastructure in little more than two weeks, after strikes on 9 and 20 January also left hundreds of thousands freezing in their flats.
"Living in Kyiv is a bit of a gamble these days," one resident of the Ukrainian capital, Rita, told the BBC.
