20 shot dead in Nigeria

A number of people taking part in a protest against police brutality have reportedly been shot dead or injured in Nigeria's biggest city, Lagos, according to a BBC report.

Quoting a witness, the BBC said soldiers opened fire on protesters on Tuesday (October 20) evening, leaving about 20 people dead and at least 50 injured. 

Amnesty International said it had obtained credible reports of deaths.

The authorities have promised an investigation into the shooting.

An indefinite 24-hour curfew has been imposed on Lagos and other regions.

Protests over a now-disbanded police unit, the Special Anti-Robbery Squad (Sars), have been continuing for two weeks.

Reacting to the shootings in Lagos, former US Secretary of State Hillary Clinton called on Nigerian President Muhammadu Buhari and the army "to stop killing young #EndSARS protesters".
