The regional body Ecowas has announced West African states are to impose immediate diplomatic and economic sanctions on Mali. It comes as rebels groups take advantage of the disorder and seize large parts of the north of the country. Ecowas had given the military junta in Bamako until Monday to step down. Jeremy Keenan - professor of social anthropology at the School of Oriental and African Studies in London - talked to RFI about the options for Mali at this time of crisis.
