State-run Anadolu news agency reported on Saturday that 178 of the 225 suspects detained during coordinated operations this week were remanded in custody pending trial. Prosecutors said another 34 suspects were released under judicial supervision, while legal proceedings involving the remaining detainees were continuing.

The arrests come ahead of the NATO summit scheduled for July 7-8 in Ankara, which is expected to bring together leaders from the alliance’s 32 member states, including U.S. President Donald Trump.

The Media and Law Studies Association (MLSA), a Turkish legal rights organization, said those detained included journalists, academics, lawyers, trade unionists, teachers, students and representatives of civil society organizations.

According to MLSA, those placed in pre-trial detention included Yildiz Tar, editor-in-chief of the LGBTQ-focused publication Kaos GL, Ankara University academic Emel Memis, and Nevzat Ozer of the TEMA Foundation, one of Türkiye’s leading environmental organizations, along with several volunteers associated with the group.

MLSA said environmental activists were questioned by police about alleged links to the banned Communist Party of Türkiye/Marxist-Leninist (TKP/ML), including whether they used code names or had received armed training.

Turkish authorities have not publicly detailed the evidence supporting the terrorism-related allegations against the detainees. The security operations follow broader counterterrorism efforts launched in the run-up to the high-profile NATO meeting, as Ankara tightens security before hosting alliance leaders.
