Kenyans are mourning environment minister John Michuki who died of heart attack aged 80 last night at the Aga Khan Hospital. President Kibaki has directed that for the next three days starting tomorrow, the national flag will fly at half mast in honour of the departed minister whose body is lying at the lee funeral home. Michuki’s death was received with shock and disbelief both in and out of parliament. Legislators today paid tribute to the late Michuki in parliament.
