The postponement was the second in the high-profile trial since it started on May 2.
On Dec. 17, Moroccan authorities found the bodies of Maren Ueland of Norway and Louisa Vesterager Jespersen of Denmark near the summit of Mount Toubkal in the High Atlas mountain range with cuts to their necks.
The crime triggered shock in Morocco and abroad.
At the trial, 24 detained defendants – 23 Moroccans and a Swiss national with Spanish citizenship face charges of premeditated murder, setting up a terrorist group and illegal possession of firearms.
At the centre of the trial are four suspects, who pledged allegiance to the Islamic State militia in a video made days before the tourists’ bodies were found.
After the second session held on Thursday in Morocco’s north-western city of Sale, the court handling terrorism cases announced adjourning the hearings in response to a request from lawyers for the families’ victims, Moroccan television station 2M reported.
The lawyers requested the court to engage the government in the case, arguing that authorities are responsible for foreigners’ safety in the country, according to the report.
Other Moroccan media said that victims’ families seek compensation from Morocco. The claim could not be independently verified.
