There has been no official death toll from the incident on Tuesday evening in which witnesses said security forces opened fire on a crowd of over 1,000 people protesting police brutality.
Nigeria's Lagos state governor has said one person died at a Lagos hospital after a shooting incident at a protest in Lekki but it was unclear if the victim was a protester.
Governor Babjide Sanwo-Olu said in a tweet that a person had died at Reddington Hospital in Nigeria's megacity of Lagos due to blunt force trauma to the head.
"This is an isolated case. We are still investigating if he was a protester," he said.
In a televised speech earlier in the day, Sanwo-Olu described the shooting as people protested against police brutality on Tuesday night as among the "darkest hours from our history as a people."
Amnesty International and other reports blamed the shooting on Nigeria's security forces.
The protests began two weeks ago after a video circulated showing a man being beaten, apparently by police officers of the Special Anti-Robbery Squad, known as Sars.
Young protesters marched in cities across Nigeria, under the banner #EndSars. In response, the government announced it would ban the anti-robbery squad, which for several years human rights groups have blamed for widespread abuses, including torture and killings.
The demonstrators have not been satisfied with the disbandment of the Sars unit and are demanding an end to abuses and respect for human rights in all parts of the police force.
Reliable proof of killing
Amnesty International said there is “credible but disturbing evidence” that security forces in Lagos had fatally shot protesters on Tuesday night at a demonstration against police brutality despite a new curfew going into effect.
The Lagos state commissioner for information, Gbenga Omotoso, said in a statement on Tuesday night that “there have been reports of shooting at the Lekki Toll Plaza following the 24-hour curfew imposed on Lagos."
“The state government has ordered an investigation into the incident,” he said.
The Lagos governor has "advised the security agents not to arrest anyone" because of the curfew that was announced earlier on Tuesday, spokesman Gboyega Akosile said in a tweet.
Information reaching us now is that a life was lost at Reddington Hospital due to blunt force trauma to the head. It is an unfortunate and very sad loss.— Babajide Sanwo-Olu (@jidesanwoolu) October 21, 2020
This is an isolated case. We are still investigating if he was a protester.
Video shown on Nigeria's Channels Television appeared to capture audio of live rounds being fired at the scene.
“While we continue to investigate the killings, Amnesty International wishes to remind the authorities that under international law, security forces may only resort to the use of lethal force when strictly unavoidable to protect against imminent threat of death or serious injury,” Amnesty International tweeted.
The development came just hours after Sanwo-Olu warned on Twitter that the growing protests against police brutality had “degenerated into a monster that is threatening the well-being of our society.”
A police statement also had warned that security forces would now “exercise the full powers of the law to prevent any further attempt on lives and property of citizens.”
The reports of fatal shootings in Lekki come after two chaotic weeks of mounting protests leading to more widespread social unrest.
On Tuesday, authorities said nearly 2,000 inmates had broken out of jail after crowds attacked two correctional facilities a day earlier.
The inspector general of police said it was deploying anti-riot police across Nigeria, which is Africa’s most populous nation, and ordered forces to strengthen security around correctional facilities.
Lagos governor said the new curfew would cover the entire city of some 14 million people and surrounding areas.
The announcement came after a police station was burned down in the city and two people were shot dead by police.
“Lives and limbs have been lost as criminals and miscreants are now hiding under the umbrella of these protests to unleash mayhem on our state,” the governor said.
Lagos has been the epicentre of the protests, with demonstrators at times blocking access to the airport and barricading roads leading to the country's main ports.
A curfew also went into effect in Benin City after a pair of attacks on correctional facilities that left 1,993 inmates missing.
Interior Ministry spokesperson Mohammed Manga said large, armed crowds had attacked the two prisons, subduing the guards on duty.
It was unclear what the prisons' exact populations had been before the attack.
“Most of the inmates held at the centres are convicted criminals serving terms for various criminal offences, awaiting execution or standing trial for violent crimes,” he said in a statement.
