(CNN) -- The authorities who control Kosovo may have stolen organs from prisoners of war and political rivals when the Kosovo Liberation Army was fighting Serbian forces for control of the territory, European authorities allege in a new report. "Numerous indications seem to confirm that ... organs were removed from some prisoners ... to be taken abroad for transplantation," according to a draft report from the Council of Europe. Investigators have "made progress" toward "proving the existence of secret KLA places of detention in northern Albania where inhuman treatment and even murders are said to have been committed," draft author Dick Marty says.

Investigators are not getting enough cooperation from either @placeholder or Kosovo, the report adds.
Kosovo has made it "complicated" to dig for missing bodies, and @placeholder has refused to allow it, Marty says, adding: "Serbia ultimately cooperated."
