Members of the Marxist-Leninist Communist Party (MLKP) terrorist organization and U.S. officials met in Syria two weeks ago, Interior Minister Süleyman Soylu said in a live broadcast on Tuesday.
The MLKP, which was founded in 1994, is on Turkey's list of "primary terror organizations".
The revelation comes amid the U.S.' continued active support to another terrorist group that targets Turkey, the People's Protection Units (YPG), which is the Syrian wing of the terror group the PKK. The PKK is considered a terrorist organization by Turkey, the U.S., and the EU.
In July 2015, the group resumed its 30-year armed campaign against the Turkish state killing over 40,000 people, including women, children and infants.
