As many as 8,040 young Kenyans have been executed or tortured to death since 2002 in a police crackdown on an outlawed sect, according to a new report by a group of Kenyan lawyers.

Another 4,070 young men have gone missing between August 2002 and August 2007 after being held in police custody, said the report by the Oscar Foundation Free Legal Aid Clinic-Kenya released Saturday.
