During November and December 2009, Amnesty International researchers travelled to Conakry in Guinea. We went to document one of West Africa’s most serious episodes of violence and human rights abuse in recent years: the ‘Bloody Monday’ massacre on 28th September 2009, when Guinean security forces opened fire with tear gas and live ammunition at protestors trapped in Conakry’s stadium, killing over 150 people and publicly raping more than 40 women.
