Morocco arrested a Swiss national on Saturday in connection with the killing of two Scandinavian women, the counter-terrorism agency said. Louisa Vesterager Jespersen, 24, from Denmark, and Maren Ueland, 28, from Norway were found dead early on Dec. 17 near the village of Imlil in the Atlas Mountains, Reuters reported. The man arrested is also suspected of “involvement in recruiting Moroccan and sub-Saharan nationals to carry out terrorist plots in Morocco against foreign targets and security forces in order to take hold of their service weapons", the Central Bureau for Judicial Investigations (BCIJ) said. More than 18 other men have been arrested in connection with the case, with four of them being main suspects who had pledged allegiance to ISIS in a video created three days before the tourists bodies were found. The last terror attack in Morocco took place in April 2011, where 17 people were killed due to the bombing of a restaurant in Marrakech. In 2017 and 2018, Morocco said it dismantled 20 militant cells planning attacks in the country.
