According to the investigators, one of the suspects joined an armed group in Syria, which later became a part of Hayat Tahrir al-Sham. In July 2012, he participated in the execution of a captured Syrian armed forces officer. The second suspect is said to have filmed the execution, intending to use the footage as propaganda.
Later in the day, the arrested suspects will be delivered to the court, which will then determine the sentence.
