A Kenyan human rights group has accused police in the coastal region including the city of Mombasa of carrying out an increasing number of extrajudicial killings.
A spokeswoman for Haki Africa, Salma Hemed, said there had been three such deaths so far this week.
She said the actions of the police were driving young people to become radicalised or join gangs.
The Kenyan authorities have rejected similar accusations in the past.
Amnesty International and Human Rights Watch have previously accused the Kenyan security forces of carrying out forced disappearances, summary killings and torture with impunity.
