Jewish cemetery in Bukhara (Uzbekistan)

The Jewish cemetery in Bukhara is the oldest and the largest Jewish burial ground in Uzbekistan. Here, too, Sephardic graves are mixed with the flat scones and Ashkenazic graves with vertical stones. In the last time stones with the pictures of the deceased are added - for orthodox Jews an abomination. I have not found literature on the history and occupancy of the cemetery.
