In 1987 Burkina Faso's president Thomas Sankara, a revolutionary leader, hero of the pan-Africa movement and fierce opponent of imperialism, was gunned down in a coup d'État. Now, 34 years later, the trial of his alleged assassins is shortly to begin in the capital Ouagadougou. As Rémi Carayol reports, the circumstances of the murder are well known. But what we still do not know is who gave the orders for Sankara's assassination, which brought his Burkina Faso revolution to a bloody end. Nor do we know the role, if any, of foreign powers - including the former colonial power France - in his demise.
On his first tour of Africa last week President Emmanuel Macron vowed to do away with France's old and discredited approach to the continent. Addressing 800 students in the Burkina Faso capital of Ouagadougou, the French head of state certainly struck a fresh tone, talked of new projects and themes and signalled the passing of an old generation. But as Mediapart's editor François Bonnet reports, the old and serious problems confronting France in its relations with Africa have not gone away.
