Two foreign Daesh members wanted by Interpol were arrested in Ankara on Monday in a police operation, sources said.
The suspects, identified by the initials AN and CV, were active members of the terror group in recent years, the sources told Anadolu Agency (AA), requesting anonymity due to media restrictions.
Police arrested a third suspect in a separate operation in Ankara.
The suspect was involved in recruiting people through online propaganda, the sources said.
Incriminating digital content found during the raid included speeches by the terror group’s ringleaders and graphic images of executions, they added.
In 2013, Turkey became one of the first countries to declare Daesh a terrorist group. The country has since been attacked by the terror group on several occasions, with more than 300 people killed and hundreds injured in at least 10 suicide attacks, seven bombings and four armed assaults.
In response, Turkey launched counter-terrorism operations at home and abroad to prevent further attacks. Last year, Ankara arrested an ISIS terrorist identified as the right-hand man of former terrorist leader Abu Bakr al-Baghdadi.
Turkish security forces also foiled the secret office structure of the terrorist group Daesh in the country, which was used to transfer funds to the families of martyrs and captives.
