Amnesty International has received a growing number of allegations of execution-style and other deliberate killings of civilians in eastern Ukraine since April 2014. This briefing documents only the handful of cases that Amnesty International has been able to report on with confidence.

It is essential that these, and other allegations, are investigated effectively and that those responsible are held accountable.
