UN Secretary-General António Guterres on Wednesday said he was closely following recent developments across Nigeria, in the wake of reports that protesters had been shot dead and wounded, and called for "an end to reported police brutality and abuses." Guterres said in a statement issued by his Spokesperson, that he condemned "the violent escalation on 20 October in Lagos which resulted in multiple deaths and caused many injuries." According to witnesses, Nigerian security forces opened fire on Tuesday night in Africa's largest city, as protests continued over a now-disbanded and discredited police unit, known as the Special Anti-Robbery Squad, or SARS. The Government has pledged to carry out further police reforms and improve police accountability. A curfew has been imposed on Lagos and other parts of Nigeria, with reports that tensions continued into Wednesday, with police across the city firing shots in the air, in an effort to disperse protesters who were defying the order to stay off the streets. The UN chief expressed his condolences to the families of the bereaved and wished a speedy recovery to those injured. He called on Nigerian authorities "to investigate these incidents and hold the perpetrators accountable." Guterres also urged security forces "to act at all times with maximum restraint while calling on protestors to demonstrate peacefully and to refrain from violence." "The Secretary-General encourages the authorities to swiftly explore avenues to de-escalate the situation", the statement continued. "He reiterates the readiness of the United Nations to support national efforts towards finding a solution." The UN human rights chief, Michelle Bachelet on Wednesday, also strongly condemned the excessive and disproportionate force by Nigerian armed forces in Lagos, in a statement issued by her office, OHCHR. She called on the Nigerian authorities to take urgent steps to deal decisively with the underlying problem of persistent violations committed by security forces, and make a far stronger effort to bring police and army personnel guilty of crimes against civilians to justice. "While the number of casualties of yesterday's shooting at the Lekki toll plaza in Lagos is still not clear, there is little doubt that this was a case of excessive use of force, resulting in unlawful killings with live ammunition, by Nigerian armed forces," Ms. Bachelet said. "Reports that CCTV cameras and lighting were deliberately disabled prior to the shooting are even more disturbing as, if confirmed, they suggest this deplorable attack on peaceful protestors was premeditated, planned and coordinated." — UN news
