A U.S. judge sentenced a leading Kenyan drug trafficker, Baktash Akasha, to 25 years in prison on Friday after he pleaded guilty last year to conspiracy to import heroin and methamphetamine and other crimes. U.S. District Judge Victor Marrero in Manhattan sentenced Akasha, 42. Prosecutors described Akasha as the leader of a crime family called the Akasha organization, a major smuggling operation connecting the poppy fields of Afghanistan to European and U.S. cities.
