A Russian drone factory, North Korean workers and allegations of slavery. DW looks at the human cost of Moscow's war machine.

As many as 12,000 North Koreans working at a Russian drone factory are victims of "gross human rights abuses and human trafficking," according to a new report. The figures were part of a joint report published on October 14 by the Washington-based Center for Strategic and International Studies (CSIS) and the Dallas-based George W. Bush Institute. It analyzes how Russia, North Korea, China and Iran are involved in expanding unmanned aerial vehicle (UAV) production at the Yelabuga plant in Tatarstan, and what each country stands to gain.
