Operations conducted by the National Intelligence Organisation and the Istanbul Police Intelligence Branch have uncovered the clandestine activities of the ISIS armed terrorist organisation. In successive operations, 175 members of the organisation were apprehended. These individuals were operating within the ‘Ideology, Finance-Funds, Cryptocurrency, Media, Propaganda’ cells and exploiting people’s emotions to collect money, which they then transferred to ISIS.
The Istanbul Police Intelligence Branch Directorate identified individuals operating under the ISIS Propaganda Cell and making pro-terrorist posts. Thirteen members of the organisation who were spreading ISIS propaganda via social media were apprehended and taken into custody. A total of 175 organisation members were detained in five operations. Searches conducted at the addresses raided during these operations resulted in the seizure of three unlicensed pistols, four rifles, 90 rifle cartridges, and numerous cutting and piercing tools that the ISIS members had planned to use in dagger and knife attacks. Also seized were numerous banned publications reflecting the terrorist organisation’s ideology and digital materials containing organisational content. All seized evidence is being examined in detail.
Ahmet Kazancı, an alleged leader of the terrorist organisation ISIS, was captured in a border region during an operation conducted by the National Intelligence Organisation (MİT) and brought to Turkey. According to information obtained from security sources, the MİT operation targeted the media structure of the “Khorasan Province” (ISKP) of ISIS.
During the operation, Kazanci, who used the code names “Abu Ubeyde” and “Abu Ibrahim”, was captured. It was established that Kazancı had replaced Özgür Altun, also known as “Abu Yasir Al Turki”, the ISIS media leader in Turkey, following Altun’s arrest.
Following MİT’s intelligence work, it was established that Kazancı had crossed from Turkey to the Afghanistan-Pakistan region to join the organisation, actively participating in camps there. It was also established that Kazancı and Özgür Altun were involved in transferring ISIS members from Turkey to the region and that Kazancı took over organisational activities after Altun’s arrest.
Following meticulous work by the National Intelligence Organisation (MİT), it was revealed that Kazancı had survived airstrikes against ISIS members in Pakistan and intended to resume his organisational activities by illegally entering Turkey. Following this, MİT launched an operation in the border region and apprehended Kazancı.
In his statement, Kazancı confessed to his relationship with Özgür Altun, the armed and ideological training he received within ISIS, and the media and propaganda activities he carried out on behalf of the organisation. Following this, he was taken by police teams to Meram State Hospital in Konya for a health check.

Mr Gürlek emphasised that, in operations carried out in Adana, Afyonkarahisar, Antalya, Balıkesir, Batman, Çanakkale, Diyarbakır, Düzce, Eskişehir, Elazığ, Erzurum, Erzincan, Gaziantep, Hatay, Istanbul, Izmir, Kahramanmaraş, Kayseri, Kırıkkale, Kilis, Kocaeli, Kütahya, Manisa, Mardin, Mersin, Osmaniye, Sakarya, Samsun, Sivas, Şanlıurfa, Trabzon, Van, Yalova and Yozgat, proceedings had been initiated against 273 suspects and 198 of them had been taken into custody.
Turkish authorities have detained nine people as part of an investigation into an attack on police outside a building housing the Israeli Consulate in Istanbul. The operations were conducted in Istanbul as well as in the provinces of Konya and Kocaeli. They were being questioned along with the two injured assailants.
A gunman was killed and two were injured in a shootout near the Israeli consulate in Istanbul, which Turkish President Recep Tayyip Erdogan called a “heinous act of terror”.
Turkish Interior Minister Mustafa Ciftci said the attackers had come to Istanbul from the city of Izmit by rental car and that two of them were brothers. He also named the gunman killed as Yunus Emre Sarban, who it said was “connected to the terrorist organisation that exploits religion”. The two injured attackers were named as Onur Ç and Enes Ç, who the interior ministry said were brothers.
In particular, Yunus Emre Sarban (32) had been indicted on ISIS charges in the past. A Turkish court, however, acquitted him on October 4, 2022. An appeal of the acquittal was rejected by the Istanbul Regional Court of Justice, with the decision becoming final on November 3, 2023.
Sarban’s case dates back to 2019, when Turkish authorities detained several suspects during a roadside check in Tekirdağ in the European part of Turkish territory. Four individuals identified only as H.T., L.D., Ö.B. and O.B. were taken into custody on suspicion of ISIS links. A forensic examination of L.D.’s mobile phone uncovered message exchanges with Sarban which indicated that L.D. had asked Sarban to help procure a rental vehicle, a mask and a weapon, raising suspicions about potential operational planning.
Following these findings, Sarban was added to the case file and arrested along with the other suspects on January 10, 2019. Prosecutors formally charged him with ISIS membership, citing evidence recovered during a search of his residence. This included books and publications allegedly supporting ISIS ideology, which authorities argued were used for purposes of recruitment and indoctrination.

Following the ISIS operation in Yalova that resulted in the deaths of three police officers, an indictment has been prepared against two suspects detained in Kocaeli. It details digital evidence, financial transactions and travel records. The prosecution has requested a prison sentence of up to 15 years for each suspect.
The indictment has been accepted and the suspects have been charged with “membership in an armed terrorist organisation”. It seeks up to 15 years’ imprisonment for each suspect on charges of ‘membership of an armed terrorist organisation’. It includes organisational posts from the digital accounts of Zafer Umutlu, one of the neutralised terrorists, as well as findings regarding his extensive communication with the suspects, financial transactions and travel records. A large-scale investigation is ongoing into the clash that occurred on 29 December 2025 in Yalova against the ISIS terrorist organisation, which resulted in the deaths of three police officers and the injury of eight police officers and one security guard. Following the incident, in which six terrorists were neutralised, operations were expanded to other provinces. On 31 December 2025, Rıza Turgay L. and Abdulmutalip Ö. were detained in simultaneous raids in Kocaeli.
The indictment, prepared by the Kocaeli Chief Public Prosecutor’s Office, details the cellular structure and internal communication network of ISIS.
According to the indictment, the Telegram account with the handle “@zafer_ebuhafsa”, which is believed to have been used by Zafer Umutlu (one of the terrorists neutralised in the Yalova clash), was examined by cybercrime units. The account had ‘La ilahe illallah’ (There is no god but Allah) written in its ‘About’ section, as well as an audio recording titled ‘El-Jihad Arabic March’. It was found to contain videos and photos of ISIS members described as ‘martyrs’, as well as organisational posts with Sharia and Jihad content. It was also determined that the account was part of a group sharing similar content.
According to information in the investigation file, Zafer Umutlu is believed to have requested a loan of 100,000 Turkish lira from Semih Can Y. in July 2025, with Y. sending a certain amount of money. Analysis of Semih Can Y.’s HTS (historical traffic data) records revealed frequent contact with Riza Turgay L. and Abdulmutalip O., who reside in Kocaeli.
It emerged that the suspects had recently travelled together in and around Yalova and were in contact with two individuals: Fatih F., a member of the İlim ve Takva Association operating in Yalova; and Mehmet İ., an alleged ISIS supporter. It was also determined that they had travelled on the Yalova–Aydın route, and this information was added to the file.
Examination of Rıza Turgay L.’s mobile phone, which was seized during the operation, revealed a video on the WhatsApp Business application showing ISIS members forming a vehicle convoy bearing the organisation’s flag.
Digital data revealed that Zafer Umutlu, one of the perpetrators of the Yalova clash, was registered in L.’s contacts as “Zafer Yalova”, and that the two had exchanged 404 WhatsApp messages between 26 February and 14 December 2025. It was also established that Rıza Turgay L. had communicated with a number registered under the name of Mehmet Cami Sordabak — another perpetrator of the clash — who was listed under a different name in his contacts.
During a search of the home of the suspect, Rıza Turgay L., in the Abdi İpekçi neighbourhood of the Darıca district, a black beret bearing Arabic writing and a metal keychain bearing similar writing, resembling flags and emblems used by ISIS, were seized.
In his statement, Rıza Turgay L. said that he was a street vendor, denied the accusations against him and claimed that he had previously been tried and acquitted of ISIS membership. He asserted that he did not know most of the individuals referenced in the investigation, that the convoy video found on his phone was likely an unintentional occurrence, and that he had purchased the items found in his home solely because they bore the word ‘Allah’. His lawyer, Gizem Dirbisoğlu, requested his client’s release and acquittal.
In its assessment, the prosecutor emphasised that the suspects, Rıza Turgay L. and Abdulmutalip Ö., had knowingly and willingly acted within the hierarchical structure of the ISIS armed terrorist organisation based on digital evidence, communications and travel records obtained. Their actions were described as continuous and intense, constituting an organisational link. Separate prison sentences ranging from 7 years and 6 months to 15 years were requested for each suspect on charges of ‘membership of an armed terrorist organisation’.
