On 28 September 2009, around 50,000 people took part in a rally to protest reported plans by military leader Moussa Dadis Camara to stand in the presidential election.

It started peacefully, until troops, under Camara’s rule entered the stadium and opened fire, killing more than 150 people.

Many others were left scarred, and women raped.

Asmaou Diallo’s son Aly was one of those killed that day, she’s been telling Megan Jones how she’s been campaigning for justice ever since.
