The humdrum of daily life in Sumy belies the constant threat of death its people have lived with since Russia invaded Ukraine three years ago.

Russian ballistic missiles ripped through the busy center of Ukraine’s northeastern city of Sumy on Sunday, officials said, killing at least 35 people and striking terror into residents who were out enjoying Palm Sunday and attending morning church services.

In the aftermath of the strike, Volodymyr Zelenskiy called on the U.S. and Europe to get tough on Russia in response to what he described as terrorism.
