Amnesty Marks 100 Days of Detention for Turkey Staff, as Ankara's Rift With West Grows
update
Human rights group Amnesty International has held events to mark 100 days since several of its Turkish staff were detained in Istanbul. Prosecutors filed terror charges against the activists this week, the latest trials in a widespread crackdown that has soured relations between Ankara and its Western allies, culminating this week in the mutual suspension of visa services between the United States and Turkey.
