A mass grave containing bones from hundreds of bodies with gunshot wounds to their skulls was discovered during construction atop what used to be the ghetto of Brest, in present-day Belarus.

Human remains belonging to men, women and children as well as clothes, shoes and other personal items were uncovered last month on the construction site managed by the contractor Pribuzhsky Kwartia, according to a report Wednesday on the Virtual Brest news site.

Mayor Alexander Rogachuk said the bones belonged to “victims of ghettos,” meaning Jews imprisoned there by the Nazis during the Holocaust. Rogachuk told the Brest news site that he is in contact with local and international Jewish groups about arranging burial for the bones at local Jewish cemeteries.
