Leading Chechen seperatist Akhmed Zakaye

London, UNITED KINGDOM: Leading Chechen seperatist Akhmed Zakayev (L) and his son Chamil (R) arrive in Regents Park Mosque to attend a funeral service for former Russian spy Alexander Litvinenko in central London, 07 December 2006. Family and friends paid their respects Thursday at the moving funeral of Russian ex-spy Alexander Litvinenko -- preceded by a memorial at a London mosque -- two weeks after his shock death. A black hearse topped with white wreaths led a funeral procession of about 10 cars to Highgate cemetery in north London -- final resting place of Karl Marx -- for the non-denominational burial, an AFP correspondent said.
