The Amnesty International has alleged that 13 people were killed during the #endbadgovernance protest across by security forces on Thursday.
The group made the allegations in a post on its X handle on Friday.
The international human rights organisation condemned, “the killing of peaceful protesters by security personnel across the country”.
According to the statement, six people were killed in Suleja in Niger State, four in Maiduguri in Borno State, and three in Kaduna State.
“The Nigerian authorities must investigate these incidents and ensure that security personnel suspected of responsibility for the deadly use of force are held to account through fair trial. Violent crackdowns on peaceful protesters is unjustified and unacceptable.
“Our findings, so far, show that security personnel at the locations where lives were lost deliberately used tactics designed to kill while dealing with gatherings of people protesting hunger and deep poverty.
“Nigerian security agencies’ unlawful attitude of using firearms as tactical tool for the management of protests must end,” the statement said.
