Turkish police have detained 361 people in operations targeting suspected members and financiers of the Islamic State in Iraq and the Levant (ISIL) across 39 provinces, the Interior Ministry announced Saturday.
The operations were carried out by provincial police counterterrorism units under the coordination of the National Police Department’s intelligence and counterterrorism divisions, Turkey’s National Intelligence Organization and public prosecutors.
The ministry accused the suspects of having previously operated within ISIL or provided financial support to the group.
Authorities did not disclose the suspects’ nationalities, identify them or provide details about their alleged activities.
Police seized unlicensed weapons and ammunition, documents linked to the group, digital material and financial assets during the raids, according to the ministry.
The operations were carried out in İstanbul, Ankara, İzmir, Antalya, Bursa, Adana, Diyarbakır, Gaziantep, Konya, Mersin and Şanlıurfa.
The Interior Ministry did not say how many suspects were detained in each province or whether prosecutors had requested their arrest pending trial.
The nationwide operation was the latest in a series of large sweeps targeting suspected ISIL networks, recruiters and financiers in Turkey.
Authorities detained 70 people in separate ISIL operations across 21 provinces on June 2, accusing them of membership in the group, financing it through individuals and alleged charities and spreading its propaganda online.
The Interior Ministry announced in May that police had detained 324 people in 47 provinces over suspected ISIL links, while another nationwide operation in April resulted in 525 detentions carried out in 56 provinces.
It is unclear whether any suspects named in the latest operation had previously been detained or investigated.
Turkey regularly conducts raids on suspected ISIL cells and financial networks, reflecting concern that the group retains the ability to recruit members, raise money and plan attacks despite losing the territory it once controlled in neighboring Syria and Iraq.
Turkey shares a border of about 900 kilometers (560 miles) with Syria and served for years as a transit route for foreign fighters traveling to join armed groups there.
ISIL has carried out several mass-casualty attacks in Turkey, including the January 2017 shooting at İstanbul’s Reina nightclub that killed 39 people and attacks in Ankara, Suruç and İstanbul that killed scores of civilians.
In December 2025 three police officers and six ISIL militants were killed during an hours-long gunfight at a house in the northwestern province of Yalova, prompting another nationwide wave of raids.
