Moroccan authorities have so far arrested 19 people in the wake of the murder of two Scandinavian women last week in the Atlas Mountains, a security source familiar with the case told Reuters on Monday.
They include the four main suspects in the crime and 15 other people accused of having connections to the alleged killers. The four main suspects, aged between 25 and 30 years, had pledged allegiance to the Islamic State (ISIS) in a video made three days before the bodies were found.
