Iraqi journalist Mohammed Rasool has been in detention in a jail in Turkey for more than two months without trial.
Along with with two British journalists, Jake Hanrahan and Philip Pendlebury, Rasool was on assignment for Vice News when arrested by Turkish authorities in the town of Diyarbakir in August on what the media organisation says are completely baseless charges of aiding a terrorist organisation.
The trio had been in the south-east of the country reporting on clashes between police and separatist Kurdish groups.
Turkey has become increasingly repressive on media freedom in recent years - often arresting journalists who report on stories which may be uncomfortable for the government and one reporter was even threatened last week for asking the president about Rasool's case. Reporters Without Borders rates Turkey 149th out of 180 countries in terms of press freedom.
While Hanrahan and Pendlebury were released a week after the arrest, Rasool, 25, has remained in detention despite increasing calls for his release.
On Wednesday, Vice News imposed a two-hour blackout on its websites across the world to increase awareness about Rasool's plight and a Change.org petition calling on Turkish president Recep Tayyip Erdogan to intervene has now attracted more than 14,000 signatures.
This isn't just an attack on Rasool, or Vice News, this is an attack on press freedom everywhere.
The only way we're going to see a positive outcome to this situation is if we take it very personally. Contact your members of Congress, contact your members of Parliament. Let them know what you think about Rasool's detention and about attacks on press freedom everywhere.
