It's been more than 40 days since Russia invaded Ukraine, beginning a long-drawn-out war which is now seeing horrific human suffering. Over the last few days, the images of hundreds of dead bodies lying around in the Ukrainian town of Bucha have stunned and shocked the world. Many of the corpses had their hands tied behind their backs and wounds to the back of their heads. Russia denied its involvement, instead accusing Ukraine of "stage-managing" the dead bodies for the western media. President Zelensky speaking at the UNSC compared Russian forces to terrorists. Will the Bucha mass killings end up being a turning point in this war?
