Moroccan police on Tuesday arrested a man suspected in the death of two female tourists from Norway and Denmark, found in the Atlas Mountains with knife wounds to the neck, the Interior Ministry said.

The women’s bodies were found on Monday in an isolated area near Imlil, on the way to Toubkal, North Africa’s highest peak and a popular hiking destination, the ministry said in a statement.

The man was arrested in Marrakech, Morocco’s largest tourist hub, and police were hunting other individuals identified as suspects.
