Hello and welcome to Neuzart from the BBC World Service, coming to you live from our studios in central London.
I'm Julian Marshall.
At the end of a week in which a US envoy was in St Petersburg talking to President Putin,
Russia has once again lashed out at Ukraine.
Thirty-four people are reported to have been killed, among them children,
and a hundred others injured when the northeastern Ukrainian city of Sumi was hit today by two Russian ballistic missiles packed with cluster munitions.
Emergency services say children are among the casualties of the attack,
which took place on the Christian Festival of Palm Sunday, what Ukrainians call Willow Sunday.
They've had to recover dead bodies from the street amid scenes of devastation,
with damaged buildings and burnt out or destroyed vehicles, including a bus.
Among the many voices of international condemnation was the US Special Envoy to Ukraine,
Keith Kellogg, who said the strikes cross any lines of decency.
Igor Shapoval is the head of the Sumi Regional Organization of the Ukrainian Red Cross Society.
Speaking at the scene, he described the rescue work.
We were on the left nearby.
We carried out the wounded, we took them away on stretchers, to hospital.
They had different degrees of severity, both moderate and severe, but we were not the only ones working.
The state emergency service was working, the military was working, and everyone was helping.
And I spoke earlier to a resident of Sumi, Ludmila Voronina.
When did she first become aware that the city had been hit?
