Turkish police have arrested nine leading human rights activists, including the local director of Amnesty International, in a raid near Istanbul.
Two trainers, from Germany and Sweden, were also arrested as they worked in a digital security workshop at a hotel.
No reason has been given for the arrests. The operation was a "grotesque abuse of power", Amnesty said.
Meanwhile, tens of thousands of people are marching from Ankara to Istanbul as part of an opposition protest.
The march, now on its 22nd day, was in reaction to the arrest of an opposition lawmaker. But it has become a wider demonstration of what many say is an erosion of democracy under President Recep Tayyip Erdogan.
Turkey remains under a state of emergency imposed after rogue army officers tried to oust Mr Erdogan in a coup on 15 July 2016. Police have jailed more than 50,000 people since then. [BBC] Read more
