RABAT, Morocco (AP) — Moroccan authorities say a total of 19 people have been arrested in connection with the murders of two Nordic tourists in the Atlas Mountains.

Boubker Sabik, a spokesman for Morocco's national security agency, says 10 new suspects were arrested over the last two days for their links with the alleged killers of 24-year-old Louisa Vesterager Jespersen from Denmark, and 28-year-old Maren Ueland from Norway.

Their bodies were found last week in their camping tent in a remote area in the Atlas Mountains. Authorities believe the hikers were killed by men affiliated with the Islamic State group.

Sabik told national television 2M on Sunday that the suspects targeted the two girls randomly and that IS didn't coordinate the killings.
