Turkey detains 200 Islamist Hizb ut-Tahrir suspects
In Friday's operation police said they confiscated a number of documents linking the suspects to the Islamist group.
Hizb ut-Tahrir seeks to unite Muslims into a pan-Islamic state but says its means are peaceful. Uzbekistan blames the group for bombings in the capital in 2004, an accusation the London-based group denies.
Turkey has in the past raided Hizb ut-Tahrir and other Islamist groups, including al Qaeda, believed to operate in predominantly Muslim Turkey.
