At least 57 Burkinabe soldiers have been arrested for their alleged involvement in a mutiny last week at a military camp outside Burkina Faso's commercial capital.

Military authorities say seven people were killed and 33 injured on Friday when government troops violently squashed the mutiny. Disgruntled soldiers demanding higher wages had looted the area near Bobo Dioulasso.

Justice Minister Jerome Traore says those arrested will be questioned about their involvement in various offences, including theft and acts of violence against individuals. Authorities are continuing to search for other soldiers involved in the mutiny.

The military intervention is the first since unrest broke out three months ago in barracks nationwide following protests against the government of longtime Burkina Faso President Blaise Compaore.
