It was during the winter of 2012 that the man in his 40s is said to have been in Syria and, according to the indictment, to have been part of a violent Islamist armed group.
During the time that the crime of international law was allegedly committed, a non-international armed conflict was going on in Syria between the state of Syria and a number of armed groups.
Together with several other people, according to the indictment, he is said to have allowed himself to be photographed and filmed standing next to a head, made victory signs and uttered insulting and derogatory words.
He is also said to have been photographed with three people while pointing a weapon at them.
The indictment also states that the images and videos must have been taken with the aim of spreading them as part of the armed group's war propaganda on the internet.
The man denies wrongdoing.
- He refutes all the accusations that have been made and considers them to be completely groundless.
There is nothing to confirm that there has been an event that constitutes a violation of international law, says Thomas Olsson, the man's defense lawyer.
The evidence includes videos from the incident and documents from the Security Police.
On the defendant's computer, several edited versions of the film material were allegedly found.
