If military rule in Guinea is not rapidly ended, there is a serious risk the country will slide into a civil war that could destabilise all West Africa. Crisis Group’s latest policy briefing focuses on the events of 28 September – when security forces killed at least 160 people in a crackdown on opposition to the military regime - and their implications for the stability of the country and the sub-region. It discusses dangerous fractures within the military and signs that various members are raising ethnic militias, warns that Guineans will not accept an attempt by the army to remain in power and calls for the end of military rule and a re-opening of the democratic transition process.
