A French air strike killed 19 civilians and three armed men at a wedding in Mali in January, a UN report says. France’s defence ministry disputed the finding, saying the 3 January strike targeted an “armed terrorist group”. France has 5,100 troops across the Sahel region to fight militants tied to al-Qaeda and the Islamic State group. The UN carried out an investigation after locals alleged that a helicopter had fired on people attending a wedding near Bounti village in central Mali. In a statement, France’s defence ministry said it had “numerous reservations about the methodology used” by UN investigators. It “maintains with consistency and reaffirms strongly” that the air strike targeted an “armed terrorist group”, the ministry added. The UN investigation was carried out by the human rights division of its mission in Mali. Its team analysed satellite images, visited the area in late January and interviewed more than 400 people.
