Police on Saturday blocked a planned prayer vigil that was to take place at August 7th Memorial Park in Nairobi.
The event, which was to start at noon along Moi Avenue was also to happen in Mombasa.
The prayer vigil had been organised by Kikao under the June 25th Youth Movement and aimed at standing in solidarity with parents of youths who lost their children or whose children were abducted during anti-government protests.
Since December last year, four young Kenyans Bernard Mbisi Kavingo, Justus Mutumwa, Martin Mwau, and Karani Muema are still missing. Thursday, a Nairobi court instructed Inspector General of Police Douglas Kanja and DCI boss Mohamed Amin to provide answers on the missing four within seven days.
