Opposition members of parliament in Burkina Faso have called on France to open its archives to look for evidence of involvement of the French secret services in the 1987 death of Thomas Sankara. The call is the latest effort in a long-running struggle to force a full and open inquiry into the assassination which brought Burkina Faso's current president, Blaise Compaoré, to power. 'Evidence presented in other countries indicates that France was involved in the death of Thomas Sankara,' said MP and lawyer Stanislas Benewindé Sankara - no relation to the former president - at a 16 July press conference in Ouagadougou, the Burkinabè capital.
