An initial day of peace talks in Belarus has now ended - with Ukraine describing the negotiations as "extremely difficult".

On the ground, Ukrainian forces are continuing to put up stiff resistance - but the authorities in Kharkiv said at least nine people had been killed and dozens injured in repeated shell attacks on residential areas.

Terrified families there, as in other cities, spending another day huddled in basements and shelters.

Warning: this report contains distressing images.
