ISTANBUL, Dec. 13 (Xinhua) -- Turkish police on Thursday detained at least 12 people in Istanbul for their suspected links to the Islamic State (IS) militant group, local media reported.

Police launched simultaneous operations in 15 different locations across the city to capture the suspects, the private Demiroren news agency said.
