Ukraine general says 'fierce' fighting inside Avdiivka

Ukraine said Friday there was fierce fighting in the beleaguered frontline city of Avdiivka and that it was preparing new positions around the industrial hub as Russia steps up attacks.

Ukraine has rushed soldiers to the embattled eastern town of Avdiivka, surrounded on three sides by Russian forces, where the military said the situation was "extremely critical".

Ukraine army chief Zaluzhny removed from post

Ukraine's top commander Valery Zaluzhny was on Thursday removed from his post, in the biggest shake-up of Kiev's military leadership since Russia's invasion began almost two years ago.

The popular general had led the Ukrainian army since the start of the war, pushing back a vastly more powerful invading force in the first months of the conflict.
