A Saudi-led coalition accused of a deadly attack on a prison in northern Yemen last week has said it is investigating the incident after denying it launched an air raid.
The coalition has said it was not behind Friday’s attack on a detention centre in the Houthi rebel heartland of Saada, in which at least 70 people were killed, according to the medical charity Doctors Without Borders (Medecins Sans Frontieres, or MSF).
