Ukrainian authorities say dozens of people, including children, have been killed by a Russian missile strike in the northeastern city of Sumy.



President Volodymyr Zelenskyy has called for more pressure on Russia, saying talks have never stopped ballistic missiles.



Ukraine says Sunday's attack on the heart of Sumy damaged houses and public transport systems. Over 30 residents were killed, including two children. More than 80 people were injured.



Zelenskyy posted footage on social media showing damaged vehicles and rescue efforts. He condemned the strikes, saying they were staged on Palm Sunday when many people were going to church.
Zelenskyy called for strong reactions from all people who seek an end to the war.



He said without the pressure on the aggressor, peace is impossible.
