July 27 (Reuters) - Ukrainian fencer Olga Kharlan has been disqualified after refusing to shake hands with Russian Anna Smirnova at the World Championships in Milan on Thursday. Kharlan, a four-time Olympic medallist and world champion, won the individual sabre bout 15-7 and then refused to shake hands with her opponent. Smirnova remained on the piste for over half an hour after the incident, speaking with a number of officials before leaving. In fencing's rules, shaking an opponent's hand is mandatory and failure to do so results in a 'black card'. The women's team sabre event begins on July 29.
