Turkish security forces arrested Tuesday five suspected ISIS terrorists in Adana, southern Turkey.

Counter-terrorism forces had launched a raid in the city after receiving information about the presence of six suspects who were reportedly fought in Syria and Iraq, security sources said.

Five were arrested, while efforts are ongoing to arrest the last suspect.

The sources did not reveal the nationalities of the detainees, who were transferred to Adana’s Security Directorate for interrogation.

Last week, security forces in Izmir, western Turkey, arrested five people suspected of carrying financing ISIS activities.

The operation was carried out based on a report by the Financial Crimes Investigation Board on the financing of the terrorist organization in Syria.

The suspects were arrested in separate areas across the province and the interrogation process is still ongoing.

Turkish security forces have continued to crack down on ISIS cells

operations targeting ISIS cells since 2017, after the terrorist organization attacked the Reina nightclub in Istanbul on New Year’s Eve, killing 69 people, most of whom were foreigners.

ISIS had previously claimed responsibility for several terrorist operations across Turkey between 2015 and 2017, killing over 300 people and injuring dozens others.

The Interior Ministry announced that between December 2015 and December 2020, 8,143 foreigners were deported on suspicion of terrorism. About 100,000 people are banned from entering the country for the same reason.
