Reports from the capital of Guinea say violence broke out among mourners and security officers during a funeral procession, on the third anniversary of the Conakry stadium massacre.

The reports say many people were wounded during Friday's clashes and at least one person suffered a gunshot wound. The Associated Press reports police used tear gas on the crowd.

The funeral procession centered on two young people killed during riots September 21 and 22. The families of the victims said security forces gunned them down, although a police official told reporters at least one of the victims was killed by a thief trying to steal the victim's motorbike.

Opposition militants marched with the funeral procession Friday despite the tense atmosphere accompanying the anniversary of the stadium massacre, in which security forces cracked down on demonstrators at a sports stadium who were protesting the presidential candidacy of then-coup leader Moussa Dadis Camara.

Human rights groups put the death toll in the 2009 incident at 157 with hundreds more injured and raped. The military estimated a much lower death toll and said the victims were mostly killed in a stampede for the exits.
