Kyiv says it's repelling Russian attacks in the east

STORY: This is what’s left of a marketplace in east Ukraine after it was destroyed by a Russian missile strike.

A large crater in the middle of the Kharkiv village - as rescue workers sift through piles and piles of rubble.

The past few weeks were a bit quieter, says this local - she didn't expect "something like this to happen again".

Two women were killed and others were wounded - including a 10-year-old girl, according to officials.

It comes as Ukraine says it's repelling constant attacks in the eastern Donbas region by Russian mercenaries.

In the frontline town of Siversk, servicemen are using the freezing temperatures and snowfall to help track Russian movements.

"The current weather conditions mean the enemy won't conduct any offensive actions. They try to hide their movements in the very front lines. So we are conducting constant air reconnaissance to fire on them with our artillery."

In his nightly video address on Sunday, President Volodymyr Zelenskiy denounced what he called Russia’s failure to observe a ceasefire it had declared for Russian Orthodox Christmas.

Ukraine never agreed to the ceasefire, calling it a Russian excuse to reinforce troops.

Both sides accused the other of continuing hostilities throughout the period.

As Moscow's invasion of Ukraine grinds towards the one-year mark, Russia's military is under pressure at home to deliver battlefield successes.

On Sunday, it said a missile strike on Kramatorsk had killed 600 Ukrainian soldiers.

But a Reuters reporter found no visible signs of casualties at the scene of the attack, billed by Moscow as revenge for a New Year's attack that killed scores of Russian soldiers.
