Turkish Police Detain Hundreds in Crackdown on Islamic State

On December 30, 2025, Turkey’s interior minister announced that authorities have apprehended 357 individuals suspected of affiliations with the Islamic State (IS) as part of a significant crackdown. This operation follows a recent violent incident in Yalova, where three police officers and six IS militants lost their lives. Turkey’s intensified actions against IS are a response to threats of planned attacks targeting the upcoming Christmas and New Year celebrations.

Widespread Police Operations

The coordinated police raids unfolded across 21 provinces, including major cities like Istanbul and Ankara. Ali Yerlikaya, the Interior Minister, confirmed these simultaneous operations and reported the detentions, although further specifics were not disclosed. The Istanbul Chief Prosecutor’s Office noted that some of the arrested individuals were directly involved in the violent encounter in Yalova. Others were allegedly plotting potential attacks as the New Year approached.

Connections to Funding and Foreign Nationals

Prosecutors revealed that several detainees are suspected of collecting funds under the pretense of charity, which was allegedly redirected to IS-linked operations in Syria. Additionally, among those taken into custody were foreign nationals with ties to IS fighters in conflict zones.

A History of Violence in Turkey

The history of IS attacks in Turkey is marked by several tragic incidents. One of the most notorious occurred on October 10, 2015, when IS suicide bombers struck a peace rally in Ankara, resulting in at least 102 fatalities and over 400 injuries. This remains the deadliest terrorist attack in the nation’s history, and proceedings related to the event are still ongoing.

Another devastating attack happened on January 1, 2017, when a gunman opened fire during New Year celebrations at the Reina nightclub in Istanbul, claiming the lives of 39 people. Between 2015 and 2017, IS was also culpable for assaults at Istanbul’s Atatürk Airport, as well as in Suruç and Diyarbakır, resulting in hundreds of civilian casualties.

Continuing Threats and Global Response

While IS has lost control over the territory it previously occupied in Iraq and Syria, its cells continue to pose a threat, executing attacks both within these regions and globally. Recently, the United States has conducted strikes against IS militants in northwest Nigeria, while Australian authorities linked a recent attack at a Hanukkah event in Sydney to inspiration drawn from the extremist group.

Conclusion

The Turkish government’s heightened response to the risks posed by IS highlights the persistent threat of terrorism within the region and the nation’s ongoing efforts to maintain security. As the New Year approaches, vigilance and proactive measures remain crucial in thwarting potential attacks.
