Turkish police on Friday detained 42 people over suspected militant links in operations across two separate provinces, security sources and media said.
Police detained 22 suspected Islamic State militants in operations across the eastern province of Elazig, security sources said.
Separately, police detained another 20 people in the southern province of Adana over alleged links to the outlawed Kurdistan Workers Party (PKK), the state-run Anadolu news agency said. It said authorities were still seeking 10 suspects.
Ankara has detained more than 5,000 Islamic State suspects and deported some 3,290 foreign militants from 95 different countries in recent years, according to Turkish officials. It has also refused entry to at least 38,269 individuals.
On Thursday, Turkish authorities detained a suspected Islamic State militant of Russian origin after he allegedly planned to use a drone to bring down a U.S. plane at the Incirlik air base, Dogan news agency said.
The government has also stepped up its operations targeting the PKK, designated a terrorist group by Turkey, the European Union and United States, since a ceasefire between the militants and the state broke down in July 2015.
The PKK launched an armed insurgency against the state in 1984 and more than 40,000 people have been killed in the conflict.
