Minister of Foreign Affairs of Ukraine Andrii Sybiha: "The Russian army killed nine people, including senior women, and injured others in a heinous attack on a civilian bus in the Sumy region. A deliberate and barbaric war crime. 

Instead of putting an end to the killing already now, as the US, Europe, Ukraine, and others propose, Putin continues to wage a war against civilians.

There should be no illusions. Pressure on Moscow must be increased to put an end to Russian terror."
