Eighty-seven people have been killed from a Russian airstrike, in what is likely Ukraine's biggest military death toll from a single strike.
Russian forces struck a barracks that housed troops at a training base in the northern Ukrainian region of Chernihiv.
While Ukrainian President Volodymyr Zelensky did not specify whether the casualties from the attack in Desna were military persons or civilians, it is likely linked to the May 17 attack on a military training centre.
