President William Ruto said Sunday Kenyan government agencies should have been able to prevent the deaths by starvation of more than 200 members of a cult in the country's coastal region, adding he took responsibility for the disaster.  Authorities have accused Paul Mackenzie, leader of the Good News International Church, of ordering his followers to starve themselves and their children to death so they could go to heaven before the end of the world.   Of the over 200, eight people died from emaciation after being rescued, while the rest have been exhumed mostly from mass graves in the incident now known as "Shakahola Forest Massacre."
