• Day two: what we know so far

Fighting has reached the suburbs and historic centre of Kyiv after a night of Russian missile attacks on the Ukrainian capital, as Moscow indicated it was ready to talk and Ukraine's president, Volodymyr Zelenskiy, pleaded for international help.

Russian forces advanced to the outskirts of the capital from three sides on Friday while Ukrainian soldiers established defensive positions at key bridges and patrolled in armoured vehicles down the city's streets watched by anxious residents.
