More than 30 settlements across Ukraine have been hit by Russian missile strikes in the last day, damaging civilian homes and critical infrastructure.
Ukrainians, including in the capital, Kyiv, are being told to avoid using electricity for several hours a day to conserve supplies.
But it is cities near the front line like Zaporizhzhia, which are relentlessly targeted by Moscow.
One of the worst attacks came last week, ripping through a block of flats in a suburb on the outskirts of the city, on Zestafonska street.
We report from block number 8 on what happened to those who lived there – and those who survived.
