article: General Gilbert Diendere's mea culpa - however sincere it may be - contains, perhaps, the first lesson of this coup. "Human lives were lost," he said, admitting that seizing power had been "a waste of time and resources for Burkina Faso." Between 10 and 20 people were killed (the exact death toll is still unknown) and more than a hundred more were left injured with bullet wounds. Coups often have a human cost that is unnecessary. Burkina Faso's coup: Who's who? Gen Diendere explained that the coup was precipitated by the interim authority's decision to prevent associates of former President Blaise Compaore from taking part in the elections, and by a plan to disband the elite presidential guard. It remains to be seen whether the transitional government will now allow Mr Compaore's allies to contest the elections, while the role of the presidential guard within the army will certainly be redefined. "The biggest mistake was to carry out this coup," he said, "because nowadays, when we talk about democracy, we can't afford such acts." This was Gen Diendere's third coup. He helped Thomas Sankara take power in 1983 and he then overthrew him, along with Mr Compaore four years later. Whether you look at Cpt Sankara's popular support or at the 27 years that Mr Compaore spent in power, you may conclude that Gen Diendere's first two coups were successful. This one was not. "We have taken lessons for the future," Gen Diendere went on to say. What is behind the coup? Why presidential guards stage coups This is the second time in less than a year that the people of Burkina Faso have succeeded in ousting those who they saw as trying to confiscate power. In October last year, when former President Compaore tried to change the constitution so he could run for another term in office, people took to the streets and forced him out. Civil society groups, and the youth in particular, have shown that in one of the world's poorest countries, democracy may come from grassroots initiatives rather than built by a power-hungry elite. The 'heroes' of Burkina Faso's revolution In today's Africa, there are military coups and what many call "constitutional coups". The Burkinabe example has certainly spread democratic hopes and actions in Africa. Benin's President Thomas Yayi Boni has since abandoned plans to change the constitution. Denis Sassou Nguesso of Congo-Brazzaville has just announced that he will hold a referendum over the very same issue. Let's see whether the vote is free and fair. Of course, it doesn't work everywhere on the continent yet but citizens are mobilising. Burundi's President Pierre Nkurunziza violently resisted months of popular discontent earlier this year. He eventually got his third term in office but at a bloody cost - dozens have been killed. His move sparked anger within the international community, including some African countries. In the Democratic Republic of Congo, grassroots activists have received support from their counterparts in Burkina Faso and Senegal but some of them have been jailed. President Joseph Kabila is widely believed to want to
