Human Rights Watch (HRW) has called on the Kenyan authorities to urgently investigate police abuse, after criticising them for failing to take any action for the recent deaths of protesters.
In March and April riot police were deployed to suppress protests called by the opposition’s Raila Odinga in Nairobi, Kisumu, Migori and Homa Bay.
He has not accepted William Ruto’s election victory last year.
HRW and Amnesty International say excessive force was used, leading to the deaths of at least 12 people.
The police said some protesters were violent or were looting.
The rights groups said most victims were bystanders. They accused the police of firing live bullets in residential areas and inside classrooms.
