Nearly 2,000 people have been sentenced to life in prison in Turkey since the July 2016.
The claim is that they are loyal to exiled Turkish figure Fethullah Gulen (who now lives in the United States).
Turkish president Recep Tayyip Erdogan claims that anyone loyal to Gulen is a national security threat, and that they are all conspiring to overthrow the Turkish government.
In recent weeks, there have been multiple police raids across the country against individuals suspected of links to the Gulen movement, especially in the armed forces.
The arrests of over 50,000 people and the sacking of tens of thousands of public sector employees since July 2016 has raised alarm in the West and among rights activists.
