Russia’s Federal Security Service (FSB) has filed a defamation lawsuit demanding that the investigative Novaya Gazeta newspaper remove reports that accused the agency of torture, the paper has said.

Novaya Gazeta has been the target of several libel lawsuits, the most recent of which came from the former head of the state-run Russian Railways, who seeks $76,000 in damages for reports linking him to high-profile corruption and an assassination.
