Amnesty International on Thursday said that Ukraine is endangering civilians in its war-fighting tactics by establishing bases and launching attacks from residential areas, including schools and hospitals.

“We have documented a pattern of Ukrainian forces putting civilians at risk and violating the laws of war when they operate in populated areas,” said Agnès Callamard, Amnesty’s secretary-general. “Being in a defensive position does not exempt the Ukrainian military from respecting international humanitarian law.”

Amnesty said that most residential areas where Ukrainian soldiers located themselves were “kilometers” away from the front lines and that there were “viable alternatives” that would not endanger civilians.
