Police said their operation was staged across 21 provinces, including Diyarbakir.

State media said police held people suspected of financing the Kurdistan Workers' Party (PKK) or roping new members into the group.

State media said the detained included people suspected of fomenting nearly 60 street protests since 2017.

The Diyarbakir Bar Association said the number of detentions could be as high as 150. These include 20 lawyers and three theatre actors, it said.

Reporters Without Borders said 11 journalists who worked with pro-Kurdish media were also detained.

The raids were believed to be the largest since 108 suspects were arrested in a similar operation in 2020.
