Amnesty International says it has deep concerns over the level of repressive policing in Kenya. The comments come after the latest demonstrations in the country last Wednesday, when the NGO says 19 people were killed and at least 500 injured after police fired on protesters. The rallies were called to mark one year since deadly protests began over a finance bill and tax rises. Amnesty says that although there was some police restraint in parts of the country last week, in the capital Nairobi the situation exploded again. Irungu Houghton, Executive Director of Amnesty International Kenya, spoke to us in Perspective.
