(Reuters) - Morocco’s general prosecutor on Thursday confirmed the authenticity of a video in which the four suspects in the murder of two Scandinavian women pledged allegiance to Islamic State and its leader Abu Bakr al-Baghdadi.

In the video, which was shared on social media, the suspects threatened to carry out attacks, the general prosecutor said in a statement.

Investigations by Morocco’s Central Bureau for Judicial Investigation also showed that the video was made last week before the killing of the two women.
