Bombs are reportedly falling on homes in the Black Sea port city of Mariupol again.
On Wednesday, a maternity and children's hospital was blown up after an airstrike according to a Telegram post from the city council.
A Ukrainian presidential advisor has said on social media that Russia is deliberately blocking the evacuation of civilians from the city because it has failed to seize the strategically-important port, per Reuters.
The publication is also reporting that a humanitarian convoy trying to reach the south-eastern city has also had to turn back because of the fighting.
Ukrainian President Volodymr Zelenskyy has blasted the Russian airstrikes on a maternity hospital in Mariupol as "genocide".
In his nightly address to the Ukrainian public, the President urged the western world to intervene.
He said: "Everything that the occupiers are doing to Mariupol is beyond atrocities. Europeans! Ukrainians! Mariupol! Today we must be united in condemning this war crime of Russia, which reflects all the evil that the occupiers have brought to our land. All of the destroyed cities and everything they've done.
"An aerial bomb on a maternity hospital is the conclusive evidence that what is happening is a genocide of Ukrainians. Europeans! You won't be able to say that you didn't see what happened to Ukrainians in Mariupol.
"You saw. You know.
"Consequently, you must strengthen sanctions against Russia so that it never has the chance to continue this genocide. You need to pressure Russia so that it sits at the negotiating table and ends this barbarous war."
