Sali, Morocco: Moroccan authorities have made five new arrests linked to the murder a week ago of two Scandinavian women in the Atlas Mountains, the country's counter-terror chief said on Monday.

The arrests were made in several cities in the kingdom, taking the total arrests linked to the double-murder to 18, said Abdelhak Khiam, head of Morocco's central office for judicial investigation.

"The two victims were stabbed, had their throats slit and were then beheaded," he told AFP.

Rabat's prosecutor has said the four main suspects pledged allegiance to Daesh in a video filmed a week before the double-murder.

The killings have shaken Norway, Denmark and Morocco. A video circulated on social networks allegedly showed the murder of one of the tourists.
