Russian missiles have struck the central city of Vinnytsia, killing at
least 20 people including three children, Ukrainian officials say.
Ninety more were reported wounded in the attack, to the south-west of
the capital Kyiv and far from any front lines in the conflict.
Three Russian missiles hit an office block and damaged residential
buildings.
Ukrainian President Volodymyr Zelensky called it "an open act of
terrorism".
The missiles hit the car park of the nine-storey office block at around
10:50 (0750 GMT), Ukraine's State Emergency Service said.
Residential buildings were also hit in the centre of Vinnytsia, which
has a population of around 370,000.
The Russian defence ministry, which denies targeting civilians, has yet
to comment on the strike.
The Ukrainian presidency said the
attack had come from Kalibr cruise missiles launched from a submarine in
the Black Sea.
