Russia-Ukraine war live: fire at major Russian oil refinery after drone attack | Ukraine

The move to oust General Valerii Zaluzhnyi, who has clashed with President Volodymyr Zelenskiy over military strategy and other issues, follows a Ukrainian counteroffensive last year that failed to recover significant amounts of Russian-held territory.

A source close to Zelenskiy’s office said the pair also have disagreed over a new military mobilisation drive, with the president opposing Zaluzhnyi’s proposal to call up 500,000 fresh troops.

The source, however, added that the process for relieving Zaluzhnyi of his post as the commander in chief of Ukraine’s armed forces was on hold for the time being as officials consider who his replacement should be.
