At least eight people have been killed in Kenya during nationwide protests against police brutality and alleged government corruption, the East African country’s National Commission on Human Rights (KNCHR), has reported.

More than 400 people, including journalists and police officers, were injured during the protests, held across 23 counties on Wednesday, the commission said in a statement.

“Most of them were treated and discharged, eighty-three (83) of them were referred for specialized treatment, eight (8) with gunshot wounds,” KNCHR stated.

Irungu Houghton, executive director of the non-profit human rights organization Amnesty International in Kenya, told Reuters that at least 16 people had been “verified as dead,” most of them “killed by police.”
