General Info:
Kasim Guler (also known as Ebu Osama el Turki) is the alleged head of the Islamic State terrorist group (ISIS) in Turkey.

Seventy-four page confessions of the Islamic State operative code-named Abu Usama al-Turki were included in the case file.

The group had planned to assassinate opposition leaders and carry out attacks on tourists, LGBTI+s and Alevis, a religious minority, according to confessions of Guler.

Main opposition Republican People’s Party (CHP) Chair Kemal Kılıçdaroğlu and Istanbul Mayor Ekrem İmamoğlu (also a member of the CHP) were the group’s targets.

Also, Cappadocia hot air balloons, a popular tourist attraction in Turkey, the İncirlik Military Base in Adana, which hosts US military personnel, and the Zöhre Ana Cemevi, an Alevi place of worship in the capital city of Ankara, were among the Islamic State targets, according to Guler.

Guler also admitted that Islamic State perpetrated the 2015 Ankara bombings, the 2014 Suruç bombings, the 2016 Antep bombing, and the 2017 nightclub shooting in Istanbul.

The Turkey’s National Intelligence Organization (MIT) initiated efforts to nab Guler on June 15 after learning that he was plotting a large-scale terrorist attack by crossing into Turkey from Syria.

Also, Guler was in the red category of the Interior Ministry’s wanted terrorist list.

It was learned that the terrorist was preparing to enter Turkey illegally with arms and explosives.

The terrorist moved to the Afghanistan–Pakistan region between 2008- 2010, and operated in conflict areas and joined the Islamic State terrorist group in 2014.
