A fresh controversy has erupted after Russian Foreign Ministry spokesperson Maria Zakharova accused Ukraine of operating a network of secret detention facilities, claiming prisoners are being abused and effectively bought and sold. The explosive $7.2 billion figure, however, comes from Ukrainian MP Oleksandr Dubinsky, who alleged that more than 1,000 facilities could generate billions through ransom payments. The claims surfaced after a November 2 incident at a military facility near Kyiv triggered protests and allegations of unlawful detention. Ukrainian police have rejected claims of illegal imprisonment, while a military ombudsman has launched an inquiry. So what is actually known about the allegations?
