Turkish security forces have detained over 760 people suspected of links to the Islamic State (IS) terrorist group.
Anti-terrorism police launched the security operation against people with alleged links to IS early Sunday, conducting simultaneous raids in 29 provinces, including İstanbul, Ankara and the border provinces of Şanlıufra and Gaziantep.
Some 450 suspects were picked up in the initial phase of the nationwide operation on Sunday but the number held has now risen to 763, the state-run Anadolu news agency said.
Anadolu quoted Turkey's police directorate as saying that IS was looking to stage a "sensational action" inside the country for propaganda purposes, with media organisations seen as a possible target.
President Recep Tayyip Erdoğan's AKP government were long critised by its opponents of not doing enough to stop the flow of jihadists across its borders and emergence of IS cells in its own cities.
