Russia attacked the northeastern city with ballistic missiles on the morning of Palm Sunday, killing at least 34 people, including two children. The strike injured at least another 117 people, including 15 children.

Brink joined the chorus of international officials speaking out in the aftermath of the attack. In a post on X, Brink said that reports indicate Russia used cluster munitions in the strike on Sumy.

“Reports indicate, as in Kryvyi Rih, cluster munitions were used, increasing the devastation and harm to civilians,” she wrote.

Russia targeted the city of Kryvyi Rih with a missile attack on April 4, killing 20 people and injuring 75. Children were among the casualties.
