There are two competing projects for a memorial at Babyn Yar, the site of a mass murder of Jews and others during the Nazi occupation. One of these projects, the Russian, is heavily funded by Kremlin allies and seeks to use the memorial to blame Ukrainian anti-Semitism for this crime against humanity.
The other, less well-funded and lacking even the enthusiastic backing of the current Ukrainian president, is being developed by a group of Ukrainians, Jewish and otherwise. Its purpose is not some information war with Russia, but rather a respectful memorial to the victims of this tragedy.
