In early May, four Ukrainian marines were accused of killing 12 civilians in Mariupol. The victims were shot with automatic small arms by the marines.

The marines are accused of shooting the civilians on the orders of the commander of the armed forces of the Donetsk People's Republic. The trial is expected to last until the end of May, according to the prosecutor's office in Donetsk. The accused are expected to appear before a court in Donetsk on May 31. The prosecution is seeking a sentence of up to 10 years in prison.
