Fighting continues in Ukraine as the two-year anniversary of Russia's invasion draws closer.
Ukraine's President Volodymyr Zelenskyy was in Davos this week for the World Economic Forum, where he addressed Western hesitation in providing further aid to Ukraine. It is the first time Mr Zelenskyy has attended the forum in person since the war began.
He urged political leaders facing war fatigue to strengthen their support for Kyiv, saying that Putin's plans go beyond Ukraine.
The BBC's James Waterhouse spoke to Charlotte Cook from Kyiv.
